A transversal cuts two parallel lines at A and B. The two interior angles at A ate bisected and so are the two interior angles at B; the four bisectors form a quadrilateral ACBD. Prove that 1) ACBD is a rectangle 2) CD is parallel to the original parallel lines.

A transversal cuts two parallel lines at A and B The two interior angle at A are bisected and so are the two interior angle at B. The four bisector form a quadrilateral ACBD. prove that ACBD us a rectangle and CD is parrel to original parral lines.
