Question

If you want to use coordinate geometry to prove that the diagonals of an isosceles trapezoid are congruent, which coordinates of the vertices would you choose for an easy proof? (0, 0), (2a, 0), (a + b, c), (a – b,

c. (0, c), (2b, c), (–a + b, 0), (a + b, 0) (–a, –c), (a, c), (b, 0), (–b, 0) (b, c), (–b, c), (–a, 0), (a, 0)

Answer 1

what you would do is you would make sure the slope of the diagonals are congruent
