(b)If AB and MN bisect each other at O and AM and BN are perpendicularsto XY, prove that Δ。AM and Δ。BN are congruent and hence prove thatAM = BN. |

Answer» AB and MN bisect each other therefore AO=BO,MO=NOin TriangleAMO and BNOangle AMO=angleBNOAO=BOMO=NOby RHS congruence rule triangleAMO and BNO are congruenttherefore triangleOAM andOBN are also congruent and hence AM = BN |
