Understanding coterminal angles in trigonometry

The video tutorial explains coterminal angles, focusing on initial and terminal sides. It covers how to calculate coterminal angles by adding or subtracting 360 degrees, and discusses both positive and negative coterminal angles. The concept of infinite coterminal angles is also explored, emphasizing the ability to find multiple angles by continuously adding or subtracting 360 degrees.

What defines coterminal angles?

• Angles that are always 90 degrees apart

• Angles with different initial sides

• Angles with the same initial and terminal sides

• Angles that are always 180 degrees apart

How can you find a negative coterminal angle?

• By subtracting the angle from 360 degrees

• By adding 360 degrees

• By subtracting the angle from 180 degrees

• By adding 180 degrees

What is the result of subtracting 120 degrees from 360 degrees?

• 120 degrees

• 240 degrees

• 360 degrees

• 480 degrees

How do you find a positive coterminal angle?

• By adding 360 degrees

• By subtracting 360 degrees

• By adding 180 degrees

• By subtracting 180 degrees

What is the positive coterminal angle of 120 degrees?

• 600 degrees

• 480 degrees

• 240 degrees

• 360 degrees

What should you do if an angle is greater than 360 degrees?

• Divide by 360 degrees

• Add 360 degrees

• Subtract 360 degrees repeatedly

• Multiply by 360 degrees

If given an angle of 600 degrees, how can you find a negative coterminal angle?

• Add 360 degrees

• Subtract 360 degrees once

• Subtract 360 degrees twice

• Subtract 180 degrees
