An equilateral triangle of side length 2 has equal angles of 60°. It can be shown that the a right angle triangle of side lengths 1, 3 and 2 will have angles 60° and 30°.

For an equilateral triangle with side length a, this formula can be combined with an application of Pythagoras Theorem to show that the area of an equilateral triangle is 3 4 a 2.

This large, nearly equilateral triangle is composed of three of the brightest stars in the sky, each belonging to its own constellation.

If you start with an equilateral triangle, you’ll find that you can rotate it by multiples of 120 degrees without changing how it looks. If you start with a circle, you can rotate it by any angle.

A pretty theorem in the latter is that all equilateral triangles in a given plane project upon another plane into triangles having the same Brocard angle.
