Types of triangles based on their sides. 1  An EQUILATERAL triangle has all three sides the same length. 2  An ISOSCELES triangle has two sides with the same length. 3  A SCALENE triangle has all three sides different lengths.
Some isosceles triangles can be equilateral if all three sides are congruent. A triangle with no two of its sides congruent is called a scalene triangle and is shown below. Another way to classify triangles is according to their angles. can be classified as an acute triangle. A triangle with one obtuse angle can be classified as obtuse triangle. A right triangle is a triangle with one right angle. Segments PQ and RP are called the legs of the right triangle and segment RQ is called the
