The hypotenuse of a right triangle has endpoints A(4, 1) and B(–1, –2). On a coordinate plane, line A B has points (4, 1) and (negative 1, negative 2). At which points could the vertex of the right angle in the triangle be located? Check all that apply. (–1, 1) (4, –2) (1, 1) (2, –2) (4, –1) (–1, 4)
