Question

in the given figure, if OA =OB, OD=OC. prove that triangle AOD =~ triangle BOC​

Answer 1

Step-by-step explanation:

In△AOD&△BCO

=>OD=OC (given)

OA=OB(given)

∠AOD=∠COB (vertically opposite)

=>△AOD≅△BOC

∠OAD=∠OBC(angles corresponding to congruent sides)

[∵ AD & BC make equal angles with the same line AB]

HenceAD∣∣BC
