100
A line that only touches the circle at one point.
What is a Tangent?
100
A line that goes from one side of a circle to the other side of a circle.
What is a Chord?
100
The angle formed by joining the endpoints of an arc to the center of the circle.
What is a central angle?
100
The number of tangents to a circle you can possibly draw from a single point outside the circle.
What is two?
200
The arc that subtends the diameter of a circle.
What is a semicircle?
200
