1. Using the given graph (on the next page) manually count the length of the legs of the triangle, then substitute them into the Pythagorean Theorem and solve for the hypotenuse length. Show the substitution and write down each step and number so I can see what you did. Round your answer to the nearest tenth.

(in graph three points are A(-9,18) B(-9,5) C(8,5) respectively),

2. Now find the coordinates of the three vertices of the triangle. One is given to you. A. _____________ B. _____________ C. _____________

3. Plug the coordinates of point A and C into the distance formula and show all algebra steps to prove you get the same answer. Round to nearest .1 also.
