Q:
# What is a triangle with two equal sides?

**A triangle with two equal sides is called an isosceles triangle.** The angles opposite the equal sides in an isosceles triangle are also equal. The third, unequal side of an isosceles triangle is called the base of the triangle.

The altitude drawn on the base of an isosceles triangle helps in finding the area of the triangle, which is half the product of the altitude and the base. If all three sides and angles of a triangle are equal, it is called an equilateral triangle. Thus, an equilateral triangle is also an isosceles triangle. It is also called an equiangular triangle.
