The video tutorial explains coterminal angles, which share the same initial and terminal sides. It demonstrates how to find coterminal angles by adding or subtracting 360 degrees for angles in degrees, and 2π for angles in radians. The tutorial also covers finding both positive and negative coterminal angles.

What is a coterminal angle?

• An angle that has a different initial side but the same terminal side.

• An angle that is always more than 180 degrees.

• An angle that has the same initial and terminal sides.

• An angle that is always less than 90 degrees.

How can you find a coterminal angle of 240 degrees?

• Add 180 degrees.

• Subtract 180 degrees.

• Subtract 360 degrees.

• Add 360 degrees.

If you start with an angle of 600 degrees, what is another coterminal angle?

• 240 degrees

• 360 degrees

• 960 degrees

• 120 degrees

How can you find a negative coterminal angle?

• Subtract 360 degrees.

• Subtract 180 degrees.

• Add 180 degrees.

• Add 360 degrees.

What is the equivalent of adding or subtracting 360 degrees when dealing with radians?

• Adding or subtracting 4π.

• Adding or subtracting π.

• Adding or subtracting 2π.

• Adding or subtracting 3π.
