The distance from Jonestown to Maryville is 180 miles, the distance from Maryville to Elm City if 300 miles, and the distance from Elm City to Jonestown is 240 miles. Do the three towns form a right triangle? Explain.
Using pythagorean theorum, check to see that
a2+b2=c2
1802 + 2402 = 3002
32,400 + 57,600 = 90,000
