Question

* In Fig 7.25, AB and CD bisect each other at O.
(1) State the three pairs of equal parts in two
triangles AOC and BOD.
(ii) Which of the following statements are true?
AAOC = ADOB
(b) AAOC # ABOD
Fig 7.25​

Answer 1

Answer:

1) OB=OA

OD=OC

<BOD=<COA

Answer 2

Step-by-step explanation:

1) OA = OB

OD = OC

∠ CAO = ∠ DBO

ii)a) AO ≠ DO

OC ≠ OB

∠ AOC ≠ ∠ DOB.

By SAS congruence rule,

Δ AOC and Δ DOB is not congruent

ii)b) AO = BO

OC = OD

∠ AOC = ∠ BOD

By SAS congruence rule,

Δ AOC ≅ Δ BOD
