An isosceles triangle is a triangle that has at least two equal sides. The two equal sides are called the legs, and the other side is called the base. The angle between the legs is called the vertex angle, and the angles between a leg and the base are called the base angles. When solving related problems, if the problem doesn't specify which side is the leg or the base, you usually need to consider different cases.
