Provide an appropriate response.Show that the points P1(2, 4), P2(5, 2), and P3(7, 5) are the vertices of a right triangle.
What will be an ideal response?
Answers will vary. One possibility: The slope of the line through P1 and P2 is -2/3. The slope of the line through P2 and P3 is 3/2. Therefore, since the product of these slopes is 
the lines are perpendicular and constitute a right angle in the triangle, making the triangle formed by these points a right triangle.
