Question

AD and BC are equal perpendiculars to a line segment AB (seefig.7.18). show that CD bisects AB.​

Answer 1

Answer:

From figure,it'sGiven,

AD and BC are perpendiculars of AB.

\mathbb{ TO \:BE \:SHOWN }TOBESHOWN :

CD bisects AB

∠BOC = ∠DOC ( ∴ Vertically opposite angles )

DA = BC

∠B = ∠A = 90°

So, by \bf{AAS}AAS congruence condition, ΔBOC ≅ ΔOAD

So,

now CO = OD

so, it bisects AB on point '\bf{O}O '

OA = OB [ by \bf{CPCT}CPCT ]
