Isosceles & Equilateral Triangle Theorems, Converses & Corollaries

Isosceles Theorem, Converse & Corollaries

This video introduces the theorems and their corollaries so that you'll be able to review them quickly before we get more into the gristle of them in the next couple videos. Also known as the Base Angle Theorem, in total these theorems also cover equilateral and equiangular triangles.
