- Triangles can be classified according to the relative lengths of their sides: 1  In an equilateral triangle, all sides are the same length. 2  In an isosceles triangle, at least two sides are equal in length. 3  In a scalene triangle, all sides and internal angles are different from one another.

- 1 A triangle with all interior angles measuring less than 90° is an acute triangle or acute-angled triangle. 2  If c is the length of the longest side, then, where a and b are the lengths of the other sides. 3  A triangle with one interior angle measuring more than 90° is an obtuse triangle or obtuse-angled triangle. An isosceles triangle has two sides of equal length. 2  An isosceles triangle also has two angles of the same measure; namely, the angles opposite to the two sides of the same length; this fact is the content of the isosceles triangle theorem, which was known by Euclid.

Trypsinization Trypsinization is the process of cell dissociation using trypsin, a proteolytic enzyme which breaks down proteins, to dissociate adherent cells from the vessel in which they are being cultured.When added to a cell culture, trypsin breaks down the proteins which enable the cells to adhere to the vessel.his process of cell culture or tissue culture requires a method to dissociate the cells from the container and each other. Trypsin, an enzyme commonly found in the digestive tract, can be used to digest the proteins that facilitate adhesion to the container and between cells.

Classifying Three Types of Triangles Isosceles triangles. An isosceles triangle has two equal sides and two equal angles. The equal sides are called legs, and the third side is the base. The two angles touching the base (which are congruent, or equal) are called base angles. The angle between the two legs is called the vertex angle.

Contents Since the sum of the angles in a triangle must be 180 o, this implies that the other two angles in a right triangle must add up to 90 o. Many special trigonometric relationships between the sides and the angles emerge as a result of this special 90 o angle. One of these relations is the so called Pythagorean Theorem. In this special type of triangle, two sides are equal to each other. 2  One can prove-as you probably did long time ago in your geometry class-that the the angles opposite to these two equal sides are also equal to each other.

- An equiangular triangle is a triangle where all three interior angles are equal in measure. Because the interior angles of any triangle always add up to 180°, each angle is always a third of that, or 60° The sides of an equiangular triangle are all the same length (congruent), and so an equiangular triangle is really the same thing as an equilateral triangle.

- It is any triangle that has two sides the same length. If all three sides are the same length it is called an equilateral triangle. 1  The unequal side of an isosceles triangle is usually referred to as the 'base' of the triangle.  The base angles of an isosceles triangle are always equal.

- Properties. 1  All three angles of an equilateral triangle are always 60°. 2  The area of an equilateral triangle can be calculated in the usual way, but in this special case of an equilateral triangle, it is also given by the formula: where S is the length of any one side.

Trigonometry/Similar,Congruent,Isosceles, and Equilateral An equilateral triangle happens also to be an isosceles triangle. If all three sides are the same length then we can certainly find two sides that are the same length! If that seems strange, well yes, it is different to other terminology we have for shapes. 'Triangle', 'square', 'pentagon', 'hexagon' are all different things. But an isosceles triangle can be an equilateral triangle, and it will be if all three sides are the same length. Testing whether a triangle is equilateral. A triangle must be an equilateral triangle if either of the following is true: 1  All three sides are the same length. 2  All three angles are the same.

Aprovocative The 3-4-5 Triangle. It is perhaps surprising that there are some right-angled triangles where all three sides are whole numbers called Pythagorean Triangles. The three whole number side-lengths are called a Pythagorean triple or triad. An example is a = 3, b = 4 and h = 5, called the 3-4-5 triangle. We can check it as follows: 3 2 +4 2 = 9 + 16 = 25 = 5 2 so a2 + b2 = h2. This triple was known to the Babylonians (who lived in the area of present-day Iraq and Iran) even as long as 5000 years ago! Perhaps they used it to make a right-angled triangle so they could make true right-angles when constructing buildings-we do not know for certain.

How Many Angles Does a Triangle Have? Isosceles triangle is a triangle in which two sides are of equal length and two angles are of equal measure. Scalene triangle is a triangle which has all sides of different length and all angles are of different measure. Now we will see how many angles does a triangle have. As we know that a triangle has 3 sides and 3 vertices and each vertex has one angle in them and therefore there are total of 3 angles in a triangle. The sum of angles of a triangle is equals to 180 0. Suppose we have a triangle ABC with three angles A, B and C at each vertex respectively then sum of these three angles will be equals to 180 0, or. Angle A + Angle B + Angle C = 180.

- An equilateral triangle is one in which all three sides are congruent (same length). Because it also has the property that all three interior angles are equal, it really the same thing as an equiangular triangle. See Equiangular triangles.

- The ratio of this triangle's longest side to its shortest side is two to one.. That is, the longest side is twice as long as the shortest side. It too is manufactured in plastic and widely used in design, drawing, and building applications. You can find an endless number of examples of right triangles. right triangle can also be an isosceles triangle--which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle.

- There may be either 2 or 3. If there are only 2, the third angle is equal to or greater than 90 degrees. (the sum of the three angles must equal 180 degrees) If there are 3, … the triangle is called an acute triangle. 3 people found this useful.

Classifying Three Types of Triangles Isosceles triangle: a triangle with at least two. sides congruent. Scalene triangle: a triangle with no two sides. congruent. Another way to classify triangles is according to their angles. A triangle with three acute angles. can be classified as an acute triangle. A triangle with one obtuse angle can be classified as obtuse triangle.

Triangle In an equilateral triangle, all sides are the same length. An equilateral triangle is also a regular polygon with all angles 60°. In an isosceles triangle, at least two sides are equal in length. An isosceles triangle also has two equal angles: the angles opposite the two equal sides. In a scalene triangle, all sides and internal angles are different from one another. By internal angles. Triangles can also be classified according to their internal angles, measured here in degrees.

- Notice it always remains an equiangular triangle. The angles A,B and C always remain equal in measure. An equiangular triangle is a triangle where all three interior angles are equal in measure. The sides of an equiangular triangle are all the same length (congruent), and so an equiangular triangle is really the same thing as an equilateral triangle. See Equilateral Triangles.

"Full text of ""A treatise on the higher plane curves: intended as a sequel to A treatise on conic sections""" Since the triangle is an isosceles triangle, where th … e base angles are congruent, we can form the equation: 2x + (x + 15) = 180 3x + 15 = 180 subtract 15 to both sides; 3x = 165 divide by 3 to both sides; x = 55 x + 15 = 55 + 15 = 70 Thus, each base angle is 55° and the vertex angle is 70°.

Triangle Triangles are uniquely determined by specifying three sides (SSS theorem), two angles and a side (AAS theorem), or two sides with an adjacent angle (SAS theorem). In each of these cases, the unknown three quantities (there are three sides and three angles total) can be uniquely determined.f a line is drawn parallel to one side of a triangle so that it intersects the other two sides, it divides them proportionally, i.e., (14). (Jurgensen 1963, p. 251). In other words, a line parallel to a side of a triangle cutting the other two sides creates a triangle similar to the first.
