Co-Terminal and Reference Angles and Radians

What are co-terminal angles?

What is a reference angle?

You are drawing an angle in standard position and you swing the terminal side until an angle of  $$147\degree$$ is made. How many more degrees can you continue swinging so that the terminal side is at the same position as the initial side?
Select all that apply.

Given the angle in standard position, which image shows the corresponding reference angle?
