Arcs

In circle O, the radius is 4, and the measure of minor arc AB is 120 degrees. Find the length of minor arc AB to the nearest integer.

• 9

• 8

• 6

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 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

Match the following

• 32^o

• measure of arc ST

• 180^o

• measure of arc RS

• 58^o

• 64^o

• 116^o

• measure of arc RST

Arc AB and Arc BC are​ ​ (a)   . Arc AB equals ​ (b)   and Arc BC equals ​ (c)   .

• congruent

Match the following

• 47

• arc EF

• 52

• m<1

• 104

• m<2

Answer explanation

arc EF = Add 58+104+94=256. Then 360 - 256 = 104

m<1 = 94/2 = 47

m<2= 104/2 = 52
