Triangles are three-sided, two-dimensional flat shapes first described in Euclid's "Elements", books 1–4, c. 300 BC. They are classified according to the lengths of their sides, and there are three main types. Basic Facts is based on an equilateral triangle, which is a regular polygon with three equal sides and three angles measuring 60°. (The other two main types are an isoscele trianle, which has two equal-sided lengths and two equal-measured angles, and a scalene triangle with all sides of different lengths, and all angles of different measurements.)
