1.	31. In the given figure, AB and CD bisect each other at o.(i) State 3 pairs of equal parts in triangleAOC and triangleBOD.(ii) Is triangleAOC = triangleBOD? Give reasons.(iii) Is AC = BD ? Give reasons.
Answer» Step-by-step explanation: The three pairs of EQUAL parts in two triangles and are: CO = DO (GIVEN) OA = OB (given ) ( As opposite angles are equal when two lines intersect.) ii) So by SAS congruency rule, that is Hence, option B is correct.

Answer»

Step-by-step explanation:

The three pairs of EQUAL parts in two triangles

and

are:

CO = DO (GIVEN)

OA = OB (given )

( As opposite angles are equal when two lines intersect.)

ii) So by SAS congruency rule,

that is

Hence, option B is correct.
