3. For the triangle shown, Kenda wrote the Pythagorean relationship as r2 = p2 + q2. Is she correct? Explain.
She's not correct because the right formula would be q2 + r2 = p2 because the longest line is labeled p2 which is opposite from the right angle which makes it the hypoteneuse.
8. Is the triangle shown a right triangle? Explain your reasoning.
No, because in this case a + b doesn't equal to 50. a + b = 60
11. The side lenghts of a triangle are 5cm, 6cm, and 8cm. Determine whether the triangle is a right triangle. Explain.
