We can call the center of the circle k.
00:04
An example of a radius would be kl.
00:08
An example of a chord.
00:10
A chord begins and ends on the circle like jl.
00:14
A diameter begins and ends on the circle but goes to the center like j .i.
00:21
A secant goes through the circle intersecting it twice like g .i.
00:31
A tangent intersects the circle at one point like g .j.
00:35
The point of tangency would be point j.
00:41
A minor arc is less than 180 degrees like arc jl.
00:47
A major arc is more than 180 degrees like arc hij.
00:57
A semicircle begins and ends at a diameter like arc jli.
01:06
A central angle has a vertex at the center of the circle like angle jkl.
01:15
And inscribed angles an angle whose vertex is on the circle like angle ijl...
