Question

Two vertices of a right triangle have coordinates (5, 12) and (11, 12) . The segment that connects these points is a leg of the triangle.

Which coordinate pair for the third vertex would create a right triangle?

​ (19, 12) ​

​ (8, 12) ​

​ (8, 20) ​

​ (11, 4) ​

Answer 1

(11,4)

Explanation:

Answer 2

in order to make a right triangle with the given vertices, the third point should make a vertical line in either of the 2 points. because the 2 points are horizontal line. in order to make a vertical line, x coordinate should be the same. so the answer is the x coordinate with either 5 or 11 in it. so among the choices, the answer is ( 11, 4)
