Answer 1

Answer:

please mark as brilliant answer hope it is clear to you

Explanation:

Let two circles with respective centers A and B intersect each other at points C and D.

We have to prove ACB = ADB

Proof: In triangles ABC and ABD,

AC = AD = 5 cm

BC = BD = 11 cm

AB = AB [Common]

ABC ABD

[SSS rule of congruency]

ACB = ADB [By CPCT]
