Is the center of the circle indicated?

- anonymous

|dw:1362963306954:dw| The black dot

- anonymous

I think if:
1. Chords are = distance from center they are congruent.
and
2. Congruent chords are = distance from center.

- Mertsj

Ok. That's what I figured. We need to use the Pythagorean Theorem to find the radius of the circle. Also we need to remember that a radius that is perpendicular to the chord bisects the chord.

What you posted is true, however, the chords in your picture are not the same length are they?

- anonymous

no. In the original pic they are not either.

- Mertsj

One of them is 4 and the other one is 8, is that right?

- anonymous

yeah

- Mertsj

So did you read what I wrote about finding the radius?

- anonymous

ya

- Mertsj

Can you find the radius?

- anonymous

yeah. well i will just have to ask my teacher about this one.

Do you think that BC is 4 or AC is 4?

- anonymous

i think bc

- Mertsj

Do you think that DE is 8 or DF is 8?

- anonymous

DE

- Mertsj

Well then, you are right congruent chords are the same distance from the center and x=2

- anonymous

ok thanks
