Angles Arcs Chords

Find the measure of Arc BC.

Find the value of x.

In the formula for arc length, the x represents...

• the arc length

• the radius

• the circumference

• the central angle

The ______ and _____ lines are the chords of this circle.

• black and yellow

• red and green

• yellow and blue

• blue and green

Identify all of the minor arcs

(there can be more than one answer - 3)

• Arc CH

• Arc FCH

• Arc FG

• Arc GHF

• Arc HGF

Find the value of x.

Identify the semicircles of this figure. (there may be more than one answer)

• Arc AB

• Arc AD

• Arc BAD

• Arc BDC

• Arc ABC

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), 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), congruent central angles:

• are 60 degrees

• have congruent points

• have congruent arcs

• spell out the word "dracula"
