Question

If AB and MN bisect each other at O and AM and BN are perpendicular on XY, prove that triangle OAM and OBN are congruent and hence prove that AM=BN

Answer 1

In triangle AOM and triangle BOM
Angle AMO = Angle BNO =90°
OM=ON( becoz MN bisect each other)
Angle AOM = Angle BON (vertically opp angles)
therefore, triangle AOM congruent to triangle BOM (by ASA)
hence, AM =BN (by cpct)
