| − | '''Isosceles''' triangles are triangles such that exactly two sides of the triangle have the same length. The term is originally greek, meaning "equal legs," since the two sides of equal length are usually referred to as the "legs" of the triangle, with the remaining side being called the "base." In Euclid's ''Elements'', triangles which are not isosceles were referred to as ''cholos'', meaning "lame."
