Question

AD and BC are equal perpendiculars to a line
segment AB (see Fig. 7.18). Show that CD bisects
AB

​

Answer 1

where इस द फिगर I can't get it

Answer 2

Answer:

it is given

ad=bc 1

ad perp ab (angle oad=90)

bs prep ab (angleobc=90)

to prove

cd bisec ab,oa=ob

proof

since line cd&ab Intersection

angle aod=angle boc (virtcally opposite angle) 2

in tri BOC&triAOD

angle BOC =angle AOD from 2

angle CBO=angle DAO ( both angle are 90 degree)

BC=AD from 1

therefore, tri BOC congreunt tri AOD (AAS Congruent)

therefore, BO=AO

hence proved
