Q14 of 32 Page 67

In Figure 5.72 which of the value l, m, n, p, q and r parallel and why?

∠ACD = ∠CDS = 114° (By alternate angles property, m and r are parallel)


∠ACQ = ∠mAB = 105° (By corresponding angles property, n and p are parallel)


∠BAC = 115° and ∠ACD = 114° (Hence they are not equal and thus l and q are not parallel)
