Positions of Terminal Sides (Degrees)

Front

What is the definition of the terminal side of an angle?

Back

The terminal side of an angle is the position of the ray after the angle has been formed, starting from the initial side, which is typically the positive x-axis.

Front

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

Back

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

Front

How do you determine the angle measure in degrees for a given terminal side?

Back

To determine the angle measure in degrees for a given terminal side, you can measure the counterclockwise angle from the positive x-axis to the terminal side.

Front

What is the angle measure for a full rotation in degrees?

Back

A full rotation is 360 degrees.

Front

What is the angle measure for a half rotation in degrees?

Back

A half rotation is 180 degrees.

Front

What is the relationship between angles that differ by 360 degrees?

Back

Angles that differ by 360 degrees are coterminal angles, meaning they share the same terminal side.

Front

What is the angle measure for a quarter rotation in degrees?

Back

A quarter rotation is 90 degrees.

Front

How can you find the reference angle for an angle greater than 360 degrees?

Back

To find the reference angle for an angle greater than 360 degrees, subtract 360 degrees from the angle until it falls within the range of 0 to 360 degrees.

Front

What is the reference angle for 240 degrees?

Back

The reference angle for 240 degrees is 240 - 180 = 60 degrees.

Front

What is the terminal side of a 30-degree angle in the coordinate plane?

Back

The terminal side of a 30-degree angle lies in the first quadrant, forming a 30-degree angle with the positive x-axis.
