anonymous · Answer

ohhh alrighty,I got C for my answer, would that be correct?

anonymous · Answer

That's radius. We want secant. Secant is just a line that goes through a circle.

anonymous · Answer

ohh CE goes through it

anonymous · Answer

or GD

anonymous · Answer

Well, if you look closely at CE, it's segment line, not line. Those things are called chord. http://schools-wikipedia.org/images/289/28932.png GD is a line. Yes, it is the answer.

anonymous · Answer

Is this clear? Sorry, I know it's a lot of terms.

anonymous · Answer

it must be AB and yep, i  understood the terms:)

anonymous · Answer

"GD is a line. Yes, it is the answer." It is GD (or DG). AB is tangent, a line in the plane of the circle that intersects the circle in exactly one point. http://ef004.k12.sd.us/ch10no17.gif
