Isosceles

They have two equal sides, but what about their angles?

This lesson will show how to use the characteristics of some special Triangles.

This lesson will discuss properties of two types of right triangles, and solve an algebra problem using the properties of an isosceles triangle.

In an equilateral triangle all sides have the same length, it is a regular polygon and all angles measure 60°. An isosceles triangle, two sides are equal in length and two angles have the same measurement.
