Types of triangles Acute triangle: In an acute triangle, all angle are less than 90 degrees, so all angles are acute angles.The following is an acute triangle. We can also name triangles using angles and sides at the same time. If a triangle has one right angle and two equal sides, we can call that triangle right isosceles triangle. If a triangle has only acute angles and no equal sides, we can call that triangle acute scalene triangle. If a triangle has two equal sides and one obtuse angle, we can call that triangle obtuse isosceles triangle. Notice that an angle cannot be obtuse and equilateral at the same time.

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.

- Identifying Triangles by their Sides. Types of triangles based on their sides. An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.

Triangles There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles: Equilateral Triangle

Triangles Side and Angles Relationship between measurement of the sides and angles in a Triangle: The largest interior angle and side are opposite each other. The same rule applies to the smallest sized angle and side and the middle sized angle and side. more.

Triangle Classification And as regard their angles, triangles may be. 1  Acute (all angles are acute) 2  Right (one angle is right) 3  Obtuse (one angle is obtuse) 4  Equiangular (all angles are equal)

Squares, Rectangles, Parallelograms and Other Polygons Every triangle is either an acute triangle, an obtuse triangle, or a right triangle. Another way to group triangles is by looking at the lengths of their sides: Equilateral triangle: An equilateral triangle is one in which all three sides have the same length.

- 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°

Acute and obtuse triangles An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles.Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.Acute and obtuse triangles are the two different types of oblique triangles —triangles that are not right triangles because they have no 90° angle.cute and obtuse triangles are the two different types of oblique triangles —triangles that are not right triangles because they have no 90° angle.

Squares, Rectangles, Parallelograms and Other Polygons Right triangle: A right triangle is one in which one of the angles is a right angle (exactly 90°). It is not hard to see that every triangle falls into exactly one of these three groups. Every triangle is either an acute triangle, an obtuse triangle, or a right triangle. Another way to group triangles is by looking at the lengths of their sides: Equilateral triangle: An equilateral triangle is one in which all three sides have the same length. Isoceles triangle: An isoceles triangle is one in which two sides have the same length. Scalene triangle: A scalene triangle is one in which all three sides have different lengths.

Types of Triangles Types of Triangles. Isosceles, Equilateral, Scalene, Obtuse... Triangles can be classified by various properties relating to their angles and sides. The most common classifications are described on this page.

Shape Each of these is divided into smaller categories; triangles can be equilateral, isosceles, obtuse, acute, scalene, etc. while quadrilaterals can be rectangles, rhombi, trapezoids, squares, etc. Other common shapes are points, lines, planes, and conic sections such as ellipses, circles, and parabolas.

triangle In Euclidean geometry the sum of the angles of a triangle is equal to two right angles (180°). If all three angles of a triangle are equal, the triangle is called equilateral. An isosceles triangle has two equal angles. A scalene triangle is one in which all three angles are different.

Triangle If c is the length of the longest side, then a 2 + b 2 > c 2, where a and b are the lengths of the other sides. A triangle with one interior angle measuring more than 90° is an obtuse triangle or obtuse-angled triangle. If c is the length of the longest side, then a 2 + b 2 < c 2, where a and b are the lengths of the other sides.

Classifying Triangles by Sides or Angles All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. The types of triangles classified by their sides are the following: Equilateral triangle: A triangle with all three sides equal in measure. In Figure 1, the slash marks indicate equal measure.

Triangle Triangles can be classified according to the relative lengths of their sides: 1  An equilateral triangle has all sides the same length. 2  An isosceles triangle has two sides of equal length. 3  A scalene triangle has all sides different lengths, or equivalently all angles are unequal.

What is a Scalene Triangle? - Definition, Properties & Examples Scalene triangles are triangles with three sides of different lengths. The math term for sides of different triangles is noncongruent sides, so you may also see this phrase in your math book. For example, a triangle with side lengths of 2 cm, 3 cm, and 4 cm would be a scalene triangle.

- 1 Thus, the measure of each angle in an equilateral triangle is 180/3, or 60 degrees, and the measure of each angle in a square is 360/4, or 90 degrees.  If the polygon is not a regular polygon, you need to know the measures of the other angles in the polygon to calculate the measure of an unknown angle.

Triangle Equilateral Triangle: A triangle with all the sides of same length is called equilateral triangle. Isosceles Triangle: A three-sided polygon with at least two sides of the same length is called isosceles triangle. Scalene Triangle: A three-sided polygon with no sides of the same length is called scalene triangle. Right Triangle: A three-sided polygon with one right angle is called right triangle.

Types of Triangles Obtuse Triangle. The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90°). In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle. Since the total degrees in any triangle is 180°, an obtuse triangle can only have one angle that measures more than 90°.
