Method 1 Find the slope of AC and the slope of BC. What do the slopes tell you about ZACB? B(-3, 7) Is AABC a right triangle? How do you know? A(4, 6) 30. Method 2 Use the Distance Formula and the Converse of the Pythagorean Theorem to determine whether AABC is a right triangle. C(0, 3) 31. Which method would you use to determine STUDENT HELP whether a given triangle is right, acute, or HOMEWORK HELP obtuse? Explain.
