What is the angle called that a golf ball hits off the wall at?

For math class, we got assigned the "golf project." The purpose of the project is to design a model of a golf course hole that has not obvious possibilities for a hole-in-one. In order to do this project, we must find out what the angle is called when the golf ball hits the wood and comes off the opposite side at the exact same angle. If you have any idea of what this angle is called, your help would be very appreciated! Thank you!What is the angle called that a golf ball hits off the wall at?incident angle
