The angles of a pentagon add up to 540. if all the angles are equal what is the size of each one?

180

Step-by-step explanation:

How many triangles do you think a 5-sided polygon will have? Here's a pentagon, a 5-sided polygon. From vertex A we can draw two diagonals which separates the pentagon into three triangles. We multiply 3 times 180 degrees to find the sum of all the interior angles of a pentagon, which is 540 degrees.
