Question

Mark makes road signs for the Department of Transportation. He does this using an oversized piece of sheet metal and a machine designed to cut the sign to the appropriate specifications. Mark needs to cut a yield sign in the shape of a regular triangle. At what angle should he set the machine to travel along the perimeter of the sign and cut at the correct angle?

Answer 1

He should set the machine at 60 degrees to travel along the perimeter.

Explanation:

A regular triangle has all its edges and angles of the same value that is each angle is 60 degrees.

So after an edge from the metal sheet is cut he has to change the angle of the machine to 60 degrees to cut the successive edge.
