Answer the question.Joe is building a deck. He nails a 10-foot, 2" by 8" board along the back of the house. He intends to use two 8-foot boards for the sides out to the corner posts. Then he will use another 10-foot board for the end. How can Joe make sure his deck is a rectangle, not a parallelogram, without checking the angles formed at the corners?
What will be an ideal response?
Joe can measure the diagonals. If they are the same then the deck will be a rectangle.
