Answer:

As described below.

Explanation:

Properties of an isosceles triangle
(1) two sides are equal
(2) Corresponding angles opposite to these sides are equal.
(3) Perpendicular drawn to the third side from the corresponding vertex will bisect the third side.
(4) Hence the altitude drawn will divide the isosceles triangle into two congruent right triangles.
(5) Equilateral triangle is a special case of an isosceles triangle with all three sides and their corresponding angles equal.
