Interior Angles On The Same Side Of Transversal
Each pair of these angles are outside the parallel lines and on the same side of the transversal.
Interior angles on the same side of transversal. Interior angle of same side of transversal are between lines i e interior on the same side of transversal i e either on left or on right 3 5 are interior angles on same side of transversal 4 6 are interior angles on same side of transversal for parallel lines interior angles on same side of transversal are supplementary. First second angle 180. I e aqr crq 180 and bqr drq 180 proof putting 1 in 2 aqr crq 180 similarly we can prove bqr drq 180 hence sum of interior angles on same side of transversal is 180 hence proved.
When a transversal intersects two lines the two lines are parallel if and only if interior angles on the same side of the transversal and exterior angles on the same side of the transversal are supplementary sum to 180. Notice that the two exterior angles shown are supplementary add to 180 if the lines pq and rs are parallel. Try this drag an orange dot at a or b.

Angles on the same side of the transversal are angles that are in one of the half planes formed by the transversal. Each pair of interior angles are inside the parallel lines and on the same side of the transversal. 5x 4x 180.
As we know that sum of interior angles on same side of transversal intersecting two parallel line is 180. Exterior angles are created where a transversal crosses two usually parallel lines. First angle second angle hence the greater of two angles is 100.
X 20 so first angle 5x 5 20 100 second angle 4x 4 20 80 on comparing both these two angles we got.
