There are two ways to classify 
triangles
1. One way to classify triangles is by 
looking at the length of their sides.
If all the sides of the triangle equal the 
same length it’s a equilateral triangle.
Here is an example of a 
equilateral triangle

Classifying triangles by the length of 
their sides.
If only two sides are of the same 
length then you have a isosceles 
triangle.
Here is an example of a isosceles 
triangle.
Notice how both sides 
labeled “c” are the 
same length.

Classifying triangles by the length 
of their sides
If all the sides of the triangle have 
different lengths then you have a scalene 
triangle.
This is a example of a scalene triangle
Notice how all the sides of 
the triangle have different 
sides.

Classifying Triangles by 
their angles
If a triangle has a angle that measures 90 
degrees then it’s a right triangle.
Here is an 
example of a 
right triangle
