Question

Four angles of a pentagon are equal and the fifth is 60°.Find the equal angles and show that two sides of the pentagon are parallel.
I have found the angles and I just want to know how to show that two sides are parallel. Do I draw the irregular pentagon?If so,how?

Answer 1

To show the sides are equal all you need to do is draw the given Pentagon.. When angles are similar so are their opposite sides so chose any equal angle and dash the side of the Pentagon that's on the other side of the angle (dash =congruence)
