How to remember the angles of the unit circle of the angles in degrees

The video tutorial explains how to calculate angles on a unit circle. It starts by introducing the basic angles of 30, 45, 60, and 90 degrees. The instructor then explains how angles increase by 30 degrees in each quadrant and by 15 degrees between specific angles. The tutorial provides a step-by-step guide to calculating angles in each quadrant, eventually completing the circle with a full 360 degrees.

What is the angle in degrees at the first position in a unit circle?

• 30 degrees

What is the angle obtained by adding 15 degrees to 120 degrees?

• 135 degrees

• 150 degrees

• 165 degrees

• 180 degrees

What is the angle in degrees after adding 30 to 180 degrees?

• 225 degrees

• 270 degrees

• 240 degrees
