A) No
B) Yes

Quizplus · Accepted Answer

The distance between (-5, 0) and (1, 2) is sqrt(36 + 4) = sqrt(40) = 2sqrt(10). The distance between (1, 2) and (5, -10) is sqrt(16 + 144) = sqrt(160) = 4sqrt(10). The distance between (-5, 0) and (5, -10) is sqrt(100 + 100) = sqrt(200) = 10sqrt(2). Since 2sqrt(10)^2 + 4sqrt(10)^2 = 10sqrt(2)^2, the points are the vertices of a right triangle.
