Question

if two parllel line intersect by a transversal then prove alternate angles are equal

Answer 1

Hi  PLM = ∠RMB ………….equation (i) (Corresponding ngles) ∠RMB = ∠SML ………….equation (ii) (vertically opposite angles) From equation (i) and (ii) ∠PLM = ∠SML  Similarly, ∠LMR = ∠ALP ……….equation (iii) (corresponding angles) ∠ALP = ∠MLQ …………equation (iv) (vertically opposite angles) From equation (iii) and (iv) ∠LMR = ∠MLQ Hence  Proved  Hope it helps
