Question

Given O below, If AB and BC are congruent, what is the measure of chord BC?

Answer 1

Since, AB and BC are the same length, the measure of the chord for BC would be 12.5 units

Answer 2

we know that

AB and BC are congruent

That means

`AB=BC` ----> equation A

we have

`AB=12.5\ units`

substitute in equation A

`BC=12.5\ units`

therefore

the answer is the option B

`12.5\ units`
