In the given figure,M is the centre of the circle,seg AD ~seg AC.Prove that-seg AB is the bisectorAof angleDAC. (Write only proof)

Answer»

In triangle APM and AQMMP = MQ ( radius )angle p = angle q ( each 90°)AM = AM ( comman side)so with SASthese two triangles are congruenthence angle MAP = MAQ ( CPCT)or Angle DAC is being bisected by AB

but MP and MQ are not radii of the circle
