Answer:

The triangle whose two sides are equal is known as Isosceles triangle.

The properties of isosceles triangle are:

  1. Two side of these triangles are always equal.
  2. The angles opposite to the equal sides are also equal.
  3. Perpendicular drawn from the third side with corresponding vertex will bisect the opposite side of the triangle.
  4. Thus this altitude divide the triangle into two congruent triangles whose one side is 90°.
