00:01 In question 6 to 11, we're going to be matching the part of the circle with a term that best describes it.

00:09 Cd.

00:11 Let's look at cd.

00:13 Now cd passes through two points of the circle and it extends infinitely in both directions.

00:21 So that is a second.

00:23 So cd is a second.

00:29 Next, g.

00:30 G is part of line f, h, which only passes through the circle at point g, and so g is a point of tangency.

00:44 A appears to be the center of the circle, because it's drawn really, it's passed through the center of the circle.

00:53 Cd, segment cd is a chord.

01:01 Segment cd is a chord.

01:06 Segment e, b is a chord that passes through the center that is called the diameter.

01:14 Ae is a radius because it's coming from the center to the circumference of the circle.

01:22 In exercises 12 to 16, we're going to use the circle to name the coordinates of the points.

01:32 Now the first point we're going to be marking is a point of tangency.

01:36 A point of tangency so we have these points up here is a point of tangency and also another one at the bottom so we have two points that would act as points of tangency and so let's start at the one at the bottom so it's at one two three three zero and another point of tangency is at three one two three four endpoints of a radius now a radius has two endpoints.

02:15 One of them is the center of the circle which is at 3 -2 and i'm just going to pick one point because there are two options.

02:28 You could either pick the one on the left or the one on the right.

02:33 So i'm going to pick the one on the right.

02:35 So that's at 4 -2...
