Learn to find the reference angle of a negative angle in terms of pi

The video tutorial explains how to interpret negative angles by considering direction, specifically moving clockwise instead of counterclockwise. It discusses representing π in terms of fourths and how to calculate additional angles by adding π/4. The concept of reference angles is introduced, focusing on measuring the distance from the X-axis. The tutorial uses π/4 as a counting measure to simplify angle calculations.

What direction do you move in when dealing with a negative angle?

• Counterclockwise

• Downwards

• Clockwise

• Upwards

How can π be represented in terms of fourths?

• 2 fourths

• 3 fourths

• 4 fourths

• 5 fourths

If you have an angle of 4π/4, what is the angle when you add an extra π/4?

• 5π/4

• 7π/4

• 8π/4

• 6π/4

What is the reference angle if the terminal side is π/4 away from the X-axis?

• π/3

• π/2

• π/4

• π/6

What is the purpose of using π/4 as a counting measure?

• To measure distance from the X-axis

• To convert angles to degrees

• To measure distance from the Y-axis

• To simplify angle calculations
