Question

PLS HELP ME!!!!!!!!!!!!!!

Two vertices of a right triangle have coordinates (3, 7) and (3, 10) . The segment that connects these points is a leg of the triangle.

Which set of coordinates for the third vertex would create a right triangle? Explain how you got your answer.


​ (4, 8) ​

​ (7, 8) ​

​ (8, 7) ​

​ (4, 4) ​

I THINK it's B. or C.

Answer 1

The answer is C
If you use the other coordinates instead of point (8,7), then you will not get a right angled traingle, but you will get other types of triangles. If you use (8,7), you will get a 90° and therefore a right angled triangle.
