Chords/Chord Angles

∠ BEC is formed inside a circle by intersecting chords. If minor arc BD = 94 and minor arc CA = 166, what is the measure of ∠ BEC?

• 44°

• 47°

• 50°

• 53°

Which number best represents an inscribed angle?

• 1

• 2

• 8

• 9

Find m∠PRQ.

• 39°

• 90°

• 51°

• 15°

Which expression can be used to solve for the unknown angle measure?

• ? = 118 – 90

• ? = (118 + 90) ÷ 2

• ? = 180 - 118

• ? = 118 + 90

Which expression can be used to solve for the unknown angle measure?

• ? = (50 + 99) ÷ 2

• ? = 50 + 99

• ? = 198 - 50

• ? = 180 - (50 + 90)

Find the measure of arc NL.

• 21°

• 42°

• 45°

• 84°

In a circle (or congruent circles), congruent central angles:

• have congruent chords

• have congruent points

• have similar names

• trunkbuster

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 (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
