1.	32% x 8%14. Construct an angle of 15° at the initial point of a given ray15. AD& BC are equal perpendicular to a line segment AB. Show that CD bisects AB.Ardt 2
Answer» In triangle OAD & OBCAD=BC (GIVEN)<OAD=<OBC (EACH=90*)<AOD=<BOC (VERTICLE OPP ANGLE)THEREFORE,TRIANGLE ODA=OCB (AAS CRITERIA) OA=OB (CPCT) So, CD bisects AB.

Answer»

In triangle OAD & OBCAD=BC (GIVEN)<OAD=<OBC (EACH=90*)<AOD=<BOC (VERTICLE OPP ANGLE)THEREFORE,TRIANGLE ODA=OCB (AAS CRITERIA)

OA=OB (CPCT)

So, CD bisects AB.
