Initial and Terminal Side in Unit Circle

Positive angles in a Unit Circle start at the initial side and rotate

• Clockwise

• Counter Clockwise

• Anti-Counter Clockwise

• Super Clockwise

A circle with a radius of 1, with its center at the origin is know as the:

• Awesome Circle

• Unit Circle

• A Perfect Circle

• Rubrics Circel

Increasing or decreasing the degree measure of an angle by an integer multiple of 360 or 2π results an a:

• Obtuse angle

• Coterminal angle

• Special Right Triangle

• Terminal Velocity

What do you call the circle with radius of 1 unit?

• small circle

• half circle

• unit circle

Answer explanation

P4 B.​ (a)   , any angle that shares the ​ (b)   side is co-terminal. So, if you were to rotate ​ (c)   than 1 revolution in the positive or negative direction you ​ (d)   create additional co-terminal angles.

• Yes

• terminal

• could

• more

• No

• initial

• less

• could not

If the unit circle is divided into 8 congruent arcs, how long is the arc subtended by the initial and terminal sides made by the 7 consecutive arcs?

What do you call to a ray in an angle that can either rotates in a clockwise or

counterclockwise direction about its endpoint?

• Initial side

• Positive side

• Stationary side

• Terminal side
