Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠C

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BC

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,△OAD is congruent to △OBC

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,△OAD is congruent to △OBCTherefore,

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,△OAD is congruent to △OBCTherefore,OA=OB

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,△OAD is congruent to △OBCTherefore,OA=OBHence,

Step-by-step explanation:From figure,In △OAD & △OBC∠B=∠A.. .....(90 o )And,∠D=∠CAnd,AD=BCSo, byASA congruence criterion rule,△OAD is congruent to △OBCTherefore,OA=OBHence, CD bisects AB

Answer 2

Question :-

AD and BC are equal perpendiculars to a line segment AB (see figure). Show that CD bisects AB.

Answer :-

In ∆BOC and ∆AOD, we have

∠BOC = ∠AOD  

BC = AD [Given]

∠BOC = ∠AOD [Vertically opposite angles]

∴ ∆OBC ≅ ∆OAD [By AAS congruency]

⇒ OB = OA [By C.P.C.T.]

i.e., O is the mid-point of AB.

Thus, CD bisects AB.
