📐 Topic Summary
Triangles are classified based on the lengths of their sides. There are three main types: equilateral, isosceles, and scalene. An equilateral triangle has all three sides equal in length. An isosceles triangle has at least two sides equal in length. A scalene triangle has all three sides of different lengths. Knowing these definitions allows you to easily categorize triangles you encounter!
