Question

4. In Fig. 8.39, OA = OB, OC = OD, angle AOB =ANGLE COD , prove that AC = BD​

Answer 1

Given:OA=OB, OC=OD, angleAOB=angleCOD

To prove:AC=BD

Proof:

angleAOB=angleCOD Given

On subtracting COB from both sides

angleAOC=angleBOD...........1

In triangles AOC & BOD

OA=OB Given

OC=OD Given

angleAOC=angleBOD From 1 ∆AOC is congruent to ∆BOD [Using SAS rule]

Therefore, AC=BD CPST

Hence Proved.
