Answer:
Step-by-step explanation:
1. Measure of angle aob is 90 degree
This is because the diagonal of a square bisect each other at 90 degree
2. If OA = 3 cm then OC = 3cm
This is because diagonals of a square bisect each other
3. Here all three congruence rules are applicable.
4. OB = 5 cm
BD = 5+5 = 10 cm
