AB and CD are two parallel lines and a transversal 'l' intersects these lines at X and Y respectively Prove that the bisectors of interior angles from a parallelogram whose each angle is 90^(@).

Angles made by a transversal with two lines

AB,CD are two parallel lines and a transversal l intersects AB at X and CD at Y Prove that the bisectors of the interior angles form a parallelogram,with all its angles right angles i.e.,it is a rectangle.

In the given figure l and m are parallel lines and t is a transversal such that angle1=135^(@) find the measure of each one of the angels angle2,angle3,angle4,angle5,angle6,angle7. AND angle8
