Triangles are the simplest polygons. They have three sides and three angles, but they can look different from one another. Because there are many kinds of triangles, there are lots of important triangle formulas, many of them more complex than others.

Proof (sort of) of Sum of interior angles theorem: When connecting all of the diagonals of a polygon, it always makes two less triangles than the number of sides (hence the n – 2).

length of a side of a triangle is less than the sum of the lengths of the other two sides. Add up the two given sides and subtract 1 from the sum to find the greatest possible measure of the third side.
