Grade 7

Q1) State the property that is used in each of the following statements?

(i) If a\ \Pi\ b, then \angle1=\angle5.

(ii) If

\angle4+\angle6, then a\ \Pi\ b.

(iii) If \angle4+\angle5=180\degree, then a\ \Pi\ b.

Solution 1:

(i): Given \angle1=\angle5

Therefore \angle1=\angle5 (Pair of corresponding angles)

(ii): Given \angle4+\angle6

Therefore a\ \Pi\ b (If pair of alternate angles are equal, then the lines are parallel)

(iii): Given \angle4+\angle5=180\degree

Therefore a\ \Pi\ b (If sum of interior angles is 180\degree, then the lines are parallel)
