Answer 1

Answer:

5)

236. ABD is a triangle right-angled at A and AC I BD. Show that

(III JAC2 = BC.DC

(II) AD2 = BD.CD

(1) AB2 = BC.BD

B

OR

Sides AB and AC and median AD of a triangle ABC are respectively proportional to sides PQ and PR

and median PM to another triangle PQR. Show that AABC-APQR

Answer 2

BD Given: ABD is a triangle right angled at A . & AC ⊥ BD To prove: AB2 = BC . BD i.e. AB/BD = BC/ AB Proof: From theorem 6.7, If a perpendicular is drawn from the vertex of the right angle to.
