Understanding Isosceles Triangles | Properties, Characteristics, and Solving Methods

legs of an isosceles triangle

In an isosceles triangle, the legs refer to the two congruent sides of the triangle

In an isosceles triangle, the legs refer to the two congruent sides of the triangle. These sides are called legs because they form the two sides of the triangle that are not the base.

The base of an isosceles triangle is the third side of the triangle, which is not congruent to the legs. The base is usually shorter in length compared to the legs.

The key property of an isosceles triangle is that the angles opposite to the legs are congruent. This means that if side AB is congruent to side AC, then angle B is congruent to angle C. This property allows us to use the symmetry of the isosceles triangle to solve various geometric problems.

You can use the Pythagorean Theorem, trigonometric ratios, or other geometric properties to find the lengths of the legs or other unknowns in an isosceles triangle.
