3.05 WarmUp - Angles in Standard Position

Front

What is the standard position of an angle in the coordinate plane?

Back

The standard position of an angle is when its vertex is at the origin and its initial side lies along the positive x-axis.

Front

How are positive angles measured in standard position?

Back

Positive angles are measured counterclockwise from the positive x-axis.

Front

How are negative angles measured in standard position?

Back

Negative angles are measured clockwise from the positive x-axis.

Front

What are co-terminal angles?

Back

Co-terminal angles are angles that share the same terminal side but have different degree measures, found by adding or subtracting full rotations (360 degrees or 2π radians).

Front

What is the degree measure of a full rotation?

Back

A full rotation is 360 degrees.

Front

What is the relationship between degrees and radians?

Back

180 degrees is equal to π radians.

Front

What is the degree measure of half a rotation?

Back

Half a rotation is 180 degrees.

Front

If an angle measures 330 degrees, what is one of its co-terminal angles?

Back

One co-terminal angle of 330 degrees is -30 degrees.

Front

What is the reference angle for an angle of 330 degrees?

Back

The reference angle for 330 degrees is 30 degrees.

Front

How do you convert degrees to radians?

Back

To convert degrees to radians, multiply the degree measure by π/180.
