Cords and Arcs

Use chords to solve for x

• x = 35^o

• x = 50^o

• x = 70^o

• x = 140^o

What is the measure of angle HKI?

• 73

• 74

• 75

Find the value of x. 14 and 18 represent the entire length of the chords

• √512

• √32

• √35

• √128

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

Two cords are congruent if and only if they are equidistant from the center

• True

• False

What is the measure of arc PQ?

• 47

• 57

• 9

• 8

• 6

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
