A line intersects two parallel lines , forming eight angles . If one of the angles has measure `a^@` , how many of the other seven angles are supplementary to it ?

Three lines intersect at a point generating six angles . If one of these angles is 90^(@) , then the number of other distinct angles is :

Two angles are supplementary and if one of the angle is 72^@ then find the other angle.

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

Theorem 6.4 : If a transversal intersects two parallel lines, then each pair of interior angles on the same side of the transversal is supplementary.

Theorem 6.4 : If a transversal intersects two parallel lines, then each pair of interior angles on the same side of the transversal is supplementary.

If two lines intersect and one of the angles so formed is a right angle, then the other three angles will not be right angles.

A line l intersects a pair of parallel lines. The exterior angles on the same side of line l are in the ratio of 5:4 . The measure of the bigger angle of the two is……………………..

If a transversal intersects two parallel lines; then each pair of consecutive interior angles are supplementary.

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