ABCD is a trapezoid, AB||CD. Since they are special triangles, they have their own characteristics. It can be proven elsewhere Prove: The mid-segment of an isosceles triangle is parallel to and half the length of the base of the triangle. In mathematics, there are two types of shapes that we learn about: isosceles triangles and right triangles. All sides 2. The midpoint of a side divides the side into two equal segments. SURVEY . If two angles of a triangle are congruent, the sides opposite those angles are congruent and the triangle is isosceles.
