What are the angles of the unit circle in degrees

The video tutorial explains how to determine angles on the unit circle using increments of 90, 45, and 30 degrees. It begins with an introduction to the unit circle and its important points, followed by a detailed explanation of how to calculate angles by adding these increments. The tutorial concludes with tips on using these methods to find angles efficiently.

What is the angle formed after one complete revolution around the unit circle?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

If you start at 0 degrees and add 45 degrees twice, what angle do you reach?

• 135 degrees

• 90 degrees

• 180 degrees

• 225 degrees

What is the angle at the midpoint between 180 degrees and 270 degrees when using 45-degree increments?

• 270 degrees

• 225 degrees

• 255 degrees

• 240 degrees

Starting at 30 degrees, what is the angle after adding 30 degrees four times?

• 210 degrees

• 180 degrees

• 150 degrees

• 120 degrees

If you continue adding 30 degrees starting from 0, what angle do you reach after 11 increments?

• 360 degrees

• 390 degrees

• 330 degrees

• 300 degrees
