What is being represented in the image?

• Interior Angles

• Inscribed Angles

• Diameter

• Concentric Circles

What is being represented in the image?

• Inscribed Angle

• Interior Angle

• Secant

• Radius

An angle is a(n) ______ if the vertex is on a circle and the sides of the angle are shords of the circle.

• right angle

• acute angle

• inscribed angle

• intercepted angle

In a circle, if a diameter is is perpendicular to a chord, then:

• it bisects the chord

• it bisects the corresponding arc

• it bisects BOTH the chord and its arc

• none of these answers are correct

In a circle, if a diameter bisects a chord (that is not a diameter), then:

• it is a secant

• it is parallel to the chord

• it is perpendicular to the chord

• it is just shaking out the sillies

• 150°

• 100°

• 210°

• 105°

Find the value of x.

• 15

• 13

• 3

• 6

What is x?

• 15

• 23

• 2

• 92

In a circle (or congruent circles), the measure of an arc is:

• equal to half of the measure of its corresponding central angle

• equal to the measure of its corresponding central angle

• equal to the measure of its circle's radii

• only calculated by taking the square root of dragon taxis
