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

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

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

{Fill in the blanks: 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? - $$s=r\theta$$ - $$\theta=\frac{s}{r}$$ + $$r=\frac{s}{\theta}$$ - $$s=\pi r$$
 * type=""}

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

{The value of θ in an angle is independent of the size of the arc length since the radius is proportional in \theta=\frac{s}{r}. + TRUE. - FALSE.

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

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

{Angles are considered dimensionless, since they are defined as the ratio of lengths. + TRUE. - FALSE.
