37. The points A(1,1) and B(5,2) in the standard (x,y) coordinate plane below are 2 vertices of △ABC, which has a right angle at B. Which of the following points could be the third vertex, C?

Answer and Explanation

Your Answer is

Correct Answer is E

Explanation

Because the slopes of two mutually perpendicular straight lines are negative reciprocals of each other, based on the known coordinates of two points, the slope of AB can be calculated first, and then the slope of BC can be calculated. Only option E is composite.
