Pics. What is the area of the pentagon if theta=54 degrees? Irregular pentagons, or pentagons with unequal sides, are more difficult to study.

There are three angles in a triangle. We've divided the pentagon into five equal triangles. Now we have many ways to find nested, similar isosceles triangles in the pentagram.

Each triangle has one angle that is 360° ÷ 5 = 72° and two equal angles (𝜃 in the diagram). The second vertex and the third can be used to create diagonals making three triangles. Irregular pentagons, or pentagons with unequal sides, are more difficult to study. A full connected pentagon is made up of a series of multiple.
