Given quadrilateral ABCD,ABllDC, diagonal AC.
we can prove that angle 1= angle 2, but cannot prove angle 3=angle4 Why is this. What must be true about the sides of the Quadrilateral in order to prove that angle 3 is congruent to angle 4?
My answer:
The sides of the quadrilateral must be parellel and that the coresponding angles are congruent to each other. Am I on the right path here? Help pleeeeeeese!
Thanks much
