what do you observe about the measures of the base angles of an isosceles triangle?
Isosceles Triangles. There are many types of triangles in the world of geometry. There is a special triangle called an isosceles triangle. In an isosceles triangle, the base angles have the same degree measure and are, as a result, equal. At the same time, if two angles of a triangle have equal measure, then the sides opposite the angles are the same length. The easiest way to define an isosceles triangle is that it has two equal sides.
