Question

if two parallel lines are intersected by a transversal prove that the bisectors of two pairs of interior angles enclosed a rectangle​

Answer 1

Answer:

Then, prove that the bisectors of two pairs of interior angles enclose a rectangle. Given: Two parallel lines AB and CD are intersected by a transversal EF in points G and H respectively. ... ∴ AOB is a line. | If the sum of two adjacent angles is 180°, then the non-common arms of the angles form a line.
