Different Types of Triangles There are several different types of triangles. You can classify a triangle by its sides and its angles. There are THREE different types of triangles based on their sides. There are FOUR different types of triangles based on their angles.

Classifying Triangles by Their Sides EQUILATERAL – 3 congruent sides ISOSCELES – at least two sides congruent SCALENE – no sides congruent 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

Can You Classify the Different Triangles in the Picture Below? Classify the following triangles: AED, ABC, ACD, ACE

The Classifications… Triangle AED = Equilateral, Equiangular Triangle ABC = Equilateral, Equiangular Triangle ACD = Isoceles, Obtuse Triangle ACE = Scalene, Right So how did you do?
