A line segment 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
An arc that is less than 180 degrees and named with 2 points.
What is a minor arc?
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?
200
Two secant lines meet in the exterior of a circle at an angle of 65 degrees. The bigger arc has a measure of 240 degrees. This is the value of the smaller arc.
What is 110?
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
The tangent line that intersects 2 circles on the same side.
What is common external tangent?
300
The size of the angle between a radius and a chord, when the chord is bisected.
What is ninety degrees?
300
The measure of an inscribed angle in relation to its intercepted arc.
What is half? (The measure of the angle is half the arc)
300
Quadrilateral ABCD is inscribed in a circle. The measure of angle ABC is 96 degrees. This is the measure of angle ADC.
What is 84 degrees.
400
A circle with an inscribed polygon.
What is a circumscribed circle?
400
The value of x when tangent segment AB = 2x + 7 and tangent segment AD = 5x - 8.
What is 5?
400
A chord that is ninety degrees to a tangent is also known as this.
What is a diameter?
400
The equation to find the measure of an angle in the exterior of a circle made by two secant lines.
What is 1/2(big arc - small arc)
400
A line segment tangent to a circle is 10 in. A line secant to the circle has length of 15 inside the circle and x outside the circle. This is the value of x.
What is 5.
500
The ratio of the circumference to the diameter of a circle
What is pi?
500
The angle a diameter makes with a tangent line.
What is right angle?
500
E is the intersection of chords AC and BD. AE = x, BE = 8, CE = 2x and DE = 9. This is the value of x.
What is 6?
500
A line is tangent to a circle at point A. Chord AB has an arc measure of 76 degrees. This is the measure of the acute angle.
What is 38 degrees?
500
The measure of an arc in a circle with a radius of 5 is 60 degrees. This is the arc length.
