A theorem involving right triangles is to be proved. a. The sides have been positioned along the coor- dinate axes as shown. y B A с X Label the coordinates of the vertices. Why is AABC a right triangle? b. Suppose that the vertices of the right triangle were assigned the coordinates (0, 0), (0, a), and (a,0). Would these coordinates be appropriate? Why or why not? ins A theorem involving right triangles is to be proved. a. The sides have been positioned along the coor- dinate axes as shown. y B A с X Label the coordinates of the vertices.
