1.	In Fig. two congruent circles with centres O and O’ intersect at A and B. If ∠AO’B = 50°, then find ∠APB.
Answer» ∠AO'B = 50° Since, both the triangle are congruent so their corresponding angles are equal. ∠AOB = AO'B = 50° Now, ∠APB = \(\frac{AOB}{2}\) ∠APB = \(\frac{50}{2}\) = 25°

In Fig. two congruent circles with centres O and O’ intersect at A and B. If ∠AO’B = 50°, then find ∠APB.

Answer»

∠AO'B = 50°

Since,

both the triangle are congruent so their corresponding angles are equal.

∠AOB = AO'B = 50°

Now,

∠APB = \(\frac{AOB}{2}\)

∠APB = \(\frac{50}{2}\)

= 25°
