Circle Arcs, Chords and Central Angles

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 (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

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

Determine the radius of a circle with a central angle of 30 degrees subtended by an arc with a length of 61

• 2.0

• 29.5

• 91.0

• 116.5

If the measure of arc ABC = 210°, what is the measure of arc AC?

• 150°

• 100°

• 210°

• 105°

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), congruent arcs:

• have congruent chords

• have congruent points

• are twice the measure of their radii

• can climb a hippo

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

In a circle, the perpendicular bisector of a chord:

• is tangent to the circle

• is the diameter

• is a right triangle

• eats frosted flakes for dinner

If Circle M is congruent to Circle O, then:

• all of their central angles must be congruent

• both circles have centers named "P"

• both circles have congruent radii

• both circles have X-Box Ones
