Question

The vertices of a triangle are A(5, –4), B(7, 0), and C(1, –2). If the triangle is a right triangle, which vertex is the right angle?

Answer 1

Vertex((5,-4)
If you draw all the points on the coordinate and connect the points, a right triangle is formed with the right angle on the coordinate (5,-4)

Answer 2

My graphing calculator tells me its not a right angle but if i were to take an educated guess it would be vortex A.


Hope this helps
