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

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.
