What is a chord that passes through the center of the circle?

• Arc

• Chord

• Diameter

• Radius

What is a portion of a circle?

• Arc

• Chord

• Diameter

• Radius

What is an arc whose measure is half of a circle?

• Major Arc

• Minor Arc

• Noah's Arc

• Semi-circle

What is an arc whose measure is less than half of a circle?

• Major Arc

• Minor Arc

• Noah's Arc

• Semi-circle

What is an arc whose measure is greater than half of a circle?

• Major Arc

• Minor Arc

• Semi-circle

What is the value of x in the figure?

• 20⁰

• 40⁰

• 80⁰

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

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 (or congruent circles), congruent central angles:

• are 60 degrees

• have congruent points

• have congruent arcs

• spell out the word "dracula"

In a circle (or congruent circles), chords that are the same distance from the center:

• are similar

• have the same name

• are congruent to each other

• are walking dead
