Step-by-step explanation:

This is true for any pentagon you have. Regular pentagons where all the sides and angles are the same will have a sum of interior angles of 540 degrees ... So if you have three triangles making up your pentagon, then your angles will always add up to 540 degrees (3 * 180 degrees).
