A transverals cuts two parallel lines at A and B. The two interior angles at A are bisected and so are the two interior angles at B, the four bisectors from a quadrilateral ACBD, prove that ABCD is parallelogram.

A transversal cuts two parallel lines PQ and RS at points A and B respectively. The two interior angles at A are bisected and so are the two interior angles at B, the four bisectors form a quadrilateral ACBD. Prove that: ACBD is a rectangle

If a transversal line cuts two parallel lines then bisector of internal angle formed a

If a transversal intersects two parallel lines; then each of alternate interior angles are equAL.

Prove that if two opposite angles and two opposite sides of any quadrilateral be parallel , then it is a parallelogram.

If a transversal intersects two parallel lines, then alternate interior angles are on the _______ side of the transversal.

In the alongside diagram,the bisectors of interior angles of the parallelogram PQRS enclose a quadrilateral ABCD.Show that:

The Bisectors of any two interior angles of a rhombus meet at

If two parallel lines are cut by a transversal, then the alternate interior angles are equal

Sum of co-interior angles between parallel lines is two right angles
