{Which formula gives the measure of an angle in radians? |type="()"} - $s=r\theta$ + $\theta =\frac{s}{r}$ - $r=\frac{s}{\theta }$ - $s=\pi r$

{Complete the sentence: |type="{}"} An angle is made of two { rays (i) _4 } with a common { endpoint (i) _8 } in a single { plane (i) _5 }.

{Which formula gives the arc length of an angle? |type="()"} + $s=r\theta$ - $\theta =\frac{s}{r}$ - $r=\frac{s}{\theta }$ - $s=\pi r$

{Fill in the blanks: |type="{}"} Angles consist of an { initial (i) _7 } and a { terminal (i) _8 } ray, and an angle { measure (i) _7 }.

{Which formula gives the length of a radius of an angle? |type="()"} - $s=r\theta$ - $\theta =\frac{s}{r}$ + $r=\frac{s}{\theta }$ - $s=\pi r$

{What is the arclength of a 45 degree angle with radius 3? |type="{}"} { 2.12 _4 }

{The value of θ in an angle is independent of the size of the arc length since the radius is proportional in <math>\theta=\frac{s}{r}. |type="()"} + TRUE. - FALSE.

{What is the measure of an angle with arclength 6 and radius 8? |type="{}"} { 48 _2 }

{What is the radius of a 60 degree angle with arclength 10? |type="{}"} { 1.67 _4 }

{Angles are considered dimensionless, since they are defined as the ratio of lengths. |type="()"} + TRUE. - FALSE. </quiz>
