Question

*Hard question!! Will give medal and fan to anyone who can help!!*

Answer 1

Um, the diameter is the center to the outside of the circle

Answer 2

So which line shows that? @Race100

Answer 3

There is only one diameter in the first one ;)

Answer 4

And then a chord is a line that touches the circle in 2 spots. It is similar to the diameter, but they don't have to be the center, unlike the diameter.

Answer 5

Oh, my bad, it's the distance from one end of the circle to another that intersects the center of the circle.

Answer 6

I think they got what you meant haha

Answer 20

I haven't done these for a while so I'm a little rusty :/

Answer 21

Oh okay :D

Answer 22

I believe there are three central angles in the first one ;)

Answer 23

"A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B thereby subtending an arc between those two points whose angle is (by definition) equal to that of the central angle itself."
