Triangles The interior angles of a triangle always add up to 180 degrees. If you make one angle bigger, another angle will become smaller: The exterior angles of a triangle always add up to 360 degrees: In every triangle, the shortest side is always opposite the smallest interior angle. The longest side is always opposite the largest interior angle. “Opposite” means that the side does not touch the point of the angle on either end. Equilateral triangles must have three angles of 60 degrees each, and all triangles with three 60 degree angles are equilateral.

Re-thinking Pythagoras: Is a triangle obtuse? In either case, notice that the right angle becomes an acute angle. This allows us to state variation #2 on the Pythagorean Theorem: Notice: an acute triangle is a triangle in which all three angles are acute. In any triangle, at least two of the angles must be acute. In an acute triangle, even the largest angle is acute. Summary. We can combine all this information in one place. Suppose a triangle has three sides such that a < b < c. Then:

Tim's Triangular Page The sum of the angles of a triangle is 180 degrees, and thus, every angle in a triangle is less than 180 degrees, and the biggest angle is at least 60 degrees. Every single side of a triangle is shorter than the sum of the lengths of the remaining two sides.

- The theorem states that the hypotenuse of a right triangle can be easily calculated from the lengths of the sides. The hypotenuse is the longest side of a right triangle. If you're given the lengths of the two sides it is easy to find the hypotenuse.

Why is it that the hypotenuse is the longest side of a right triangle? The word derives from the Greek. The longest side of a right-angled triangle is called the hypotenuse which is why the hypotenuse is always the longest side of a right-angled triangle.

The Geometry of Triangles The Pythagorean Theorem: This formula is for right triangles only!The sides, a and b, of a right triangle are called the legs, and the side that is opposite to the right (90 degree) angle, c, is called the hypotenuse. This formula will help you find the length of either a, b or c, if you are given the lengths of the other two.

Hypotenuse: Definition & Formula In geometry, a hypotenuse is the longest side of a right triangle. It's also the side opposite the right angle. The word hypotenuse means 'length under' or 'stretch under.' Its earliest use was thought to be by Plato in approximately 400 BC. The length of the hypotenuse can be found by using the Pythagorean Theorem.

- The name hypotenuse is given to the longest edge in a right-angled triangle. (It is the edge opposite to the right angle and is c in this case.) Where (for brevity) it says 'edge a', 'angle B' and so on, it should, more correctly, be something like 'length of edge a' or 'edge-length' or 'size of angle B' etc.

Use the Pythagorean Theorem for Right Triangles... The theorem states that the hypotenuse of a right triangle can be easily calculated from the lengths of the sides. The hypotenuse is the longest side of a right triangle. If you're given the lengths of the two sides it is easy to find the hypotenuse.nswer : Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is [tex]a^2+b^2=c^2[/tex], which is known as the Pythagorean Theorem.

Acute and obtuse triangles This implies that the longest side in an obtuse triangle is the one opposite the obtuse-angled vertex. An acute triangle has three inscribed squares, each with one side coinciding with part of a side of the triangle and with the square's other two vertices on the remaining two sides of the triangle.

- So, a is opposite A; b is opposite B; c is opposite C. Again, the small letter could be identifying the edge or the length of the edge. Here it is the length. The name hypotenuse is given to the longest edge in a right-angled triangle. (It is the edge opposite to the right angle and is c in this case.) Where (for brevity) it says 'edge a', 'angle B' and so on, it should, more correctly, be something like 'length of edge a' or 'edge-length' or 'size of angle B' etc.

Law of Sines Law of Sines. In any triangle, there is a relationship between the measures of the angles and the lengths of the sides: the largest angle is opposite the longest side, the second-largest angle is opposite the second-longest side, and the smallest angle is opposite the shortest side.[Click to view A More Mathematical Explanation].iven a triangle with side lengths and opposite angles, The law of sines is used to find all of the lengths of the sides and the angle measures for an arbitrary triangle given only some of this information.

Triangle 1 A triangle with one interior angle measuring more than 90° is an obtuse triangle or obtuse-angled triangle. 2  If c is the length of the longest side, then, where a and b are the lengths of the other sides. If the legs of a right triangle have the same length, then the angles opposite those legs have the same measure. 2  Since these angles are complementary, it follows that each measures 45 degrees. 3  By the Pythagorean theorem, the length of the hypotenuse is the length of a leg times √2.

- 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.

Right Triangles, Acute Triangles and Obtuse Triangles An equilateral triangle is always an acute triangle since all its angles are 60° which are acute angles. Obtuse Triangles. An obtuse triangle has one obtuse angle (i.e. greater than 90°). The longest side is always opposite the obtuse angle. In the obtuse triangle shown below, a is the obtuse angle. Since the sum of all the angles in a triangle is 180º, only one angle in the triangle can be an obtuse angle , the other two angles must be acute angles.

Triangles The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. This means that they have the same angles.
