A video by yourteacher - Students learn that an isosceles triangle is composed of a base, two congruent legs, two congruent base angles, and a vertex angle. Students also learn the isosceles triangle theorem, which states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent;
