Answer:
The triangle whose two sides are equal is known as Isosceles triangle.
The properties of isosceles triangle are:
- Two side of these triangles are always equal.
- The angles opposite to the equal sides are also equal.
- Perpendicular drawn from the third side with corresponding vertex will bisect the opposite side of the triangle.
- Thus this altitude divide the triangle into two congruent triangles whose one side is 90°.
