Q37 of 113 Page 128

In Fig. 5.30, line l intersects two parallel lines PQ and RS. Then, which one of the following is not true?

According to this figure


∠ 1 = ∠ 3 (Corresponding angles)


∠2 = ∠4 (Corresponding angles)


∠6 = ∠5 (Vertically Opposite angle)


∠5 = ∠7 (Corresponding angles)


So we can say


∠6 = ∠7


∠2 and ∠8 are supplementary pair


Since ∠2 = ∠4


So ∠4 and ∠8 are also supplementary pair


Hence ∠4≠∠8
