Answer:

use SSS

Explanation:

Given two congruent chords AB and BC in circle O, you want to prove ∆AOB is congruent to ∆COB.

Statement . . . . Reason

1. circle O, AB≅BC . . . . given

2. OB ≅ OB . . . . reflexive property of congruence

3. OA ≅ OC . . . . definition of a circle

4. ∆AOB ≅ ∆COB . . . . SSS postulate

__

Additional comment

Your erased statement 2 shows you know exactly how to do this.

All the radii of a circle are the same length, so it is easy to show congruence by SSS, given that AB≅BC.
