When you finish your quiz on a separate sheet of paper work on the following: A football field is 100 yards with 10 yards at each end for the end zones. The field is 45 yards wide. Find the length of the diagonal of the entire field, including the end zones. Find the distance across Lake James, using the diagram to the right 

How could I find the perimeter of the triangle?

What about finding the area?

How can I find distance between the two points?

Find the distance between the two ordered pairs: A(-2, 4) and B is (3, 5) Graph the ordered pairs Create a right triangle Use Pythagorean Theorem to find the missing side length.

Practice: Find the distance between: 1. A(-4, -3) and B(2, 3) 2. C(4, -3) and D(-3, 4)
