Different Types of Triangles There are several different types of triangles. You can classify a triangle by its SIDES or its ANGLES.

Classifying Triangles by Their Sides EQUILATERAL – 3 congruent sides ISOSCELES – at least two sides congruent SCALENE – no sides congruent (all the sides are different lengths) EQUILATERAL ISOSCELES SCALENE

Classifying Triangles by Their Angles EQUIANGULAR – all angles are congruent ACUTE – all angles are acute RIGHT – one right angle OBTUSE – one obtuse angle EQUIANGULAR ACUTE RIGHT OBTUSE
