Student (waving me over): Miss, I have a question about this problem. (Points to question that reads One of the sides of a pentagon has length 10. The lengths of the other four sides are each equal to a sixth of its perimeter. What is the perimeter of the pentagon?). How many sides does a pentagon have?”Me (reading aloud): Well, let’s see – ONE of the sides of a pentagon has length 10. The lengths of the OTHER FOUR SIDES are each equal to a sixth of its perimeter.”Student (pauses for a second, and then looks up): Oh, okay, cool, thanks, I get it now!
