100
To cut in half.
What is "to bisect"?
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?

200

The arc that is created by the diameter of a circle.

What is a semicircle?

200
The point where a tangent touches a circle.
What is a Point of Tangency?
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?

300
A straight line that goes from one side of the circle to the other side of the circle through the center.
What is a Diameter?
300

What angle does a tangent and a radius of a circle make?

What is 90 degrees?

300

If two chords are intercepted by congruent central angles, then these chords are

What congruent?

300

These types of angles are equal when they correspond to the same arc

What are Inscribed Angles?

400
A tool used for measuring angles.
What is a protractor?
400
Four tangents to a circle make this figure when they are ninety degrees to teach other.
What is a square?
400

A chord that is ninety degrees to a tangent is also known as this.

What is a diameter?

400

This angle is twice the inscribed angle when they correspond to the same arc.

What is a Central Angle?

500
A tool used for drawing circles.
What is a compass?
500

How many tangent lines can be drawn from one external point to a circle?

What is two?

500

If you were to draw two different chords and bisect them, the two bisectors would intersect at this point.

What is the center (origin) of the circle?

500

All inscribed angles that correspond to a semicircle are this.

What are Right Angles?
