100
Degrees in a circle.
What is 360?
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 degrees of the arc that connects the diameter of a circle.
What is a semicircle
1800?
200
What is 5? Tangent segments that meet at an external endpoint are congruent.
200
The radius does this to a chord when they are perpendicular.
What is bisect?
200
The angle formed by joining the endpoints of an arc to a point on the circle.
What is an Inscribed Angle?
200
What is x=17.55? chords that meet at a common external endpoint - external segment x whole segment = external segment x whole segment

300
Find Angle B
60o? Tangent segments that meet at an external endpoint form an angle that is 1/2 the difference of major and minor arc.
300
.
43o? When chord intersect they form an angle that is 1/2 the sum of the intercepted arcs.
