## Which quadrant does the angle lie?

An angle in standard position is said to lie in a quadrant if its terminal side lies in that quadrant.

In the figures below, apha lies in the 1st quadrant, β lies in the 2nd quadrant, γ lies in the 3rd quadrant and θ lies in the 4th quadrant..

## What’s a Coterminal angle?

Coterminal angles: are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side.

## What is the standard position?

: the position of an angle with its vertex at the origin of a rectangular-coordinate system and its initial side coinciding with the positive x-axis.

## How do you find the Coterminal angle on a calculator?

One method is to find the coterminal angle in the [0,360°) range (or [0,2π) range), as we did in the previous paragraph (if your angle is already in that range, you don’t need to do this step). Then just add or subtract 360°, 720°, 1080°…

## What does a negative angle look like?

Same distance, different directions. a positive angle starts from an initial side and moves clockwise to its terminal side. A negative angle starts from an initial side and moves counterclockwise to its terminal side.

## Are 185 and Coterminal angles?

185° and -175° Coterminal Angles Illustration showing coterminal angles of 185° and -175°. Coterminal angles are angles drawn in standard position that have a common terminal side. In this illustration, both angles are labeled with the proper degree measure.

## What is the Coterminal angle of 420?

Trigonometry Examples Subtract 360° 360 ° from 420° 420 ° . The resulting angle of 60° 60 ° is positive, less than 360° 360 ° , and coterminal with 420° 420 ° .

## Do negative degrees exist?

You can have negative angles. The standard convention is that positive angles correspond to the counter-clockwise direction. An angle of +56 degrees from the x-axis would correspond to a point in the first quadrant while an angle of -56 degrees from the x-axis would correspond to a point in the fourth quadrant.

## What is the Coterminal angle of 60?

Therefore, 60 degrees and -300 degrees are coterminal angles. The -300 degree rotation is pictured here. Infinitely many other angles are coterminal to 60 degrees. Each time you add or subtract a multiple of 360 degrees to 60 degrees, you will end up with a coterminal angle of 60 degrees.

## What is a negative angle?

Definition. Negative Angle. A negative angle is an angle measured by rotating clockwise (instead of counterclockwise) from the positive @$x@$ axis.

## How do you turn a negative into a positive?

When measured in the negative direction its will be -90°. We simply subtract 270 from 360. Given a negative angle, we add 360 to get its corresponding positive angle. When an angle is -360°, it implies that the object made more than one cycle in clockwise direction.

## What does Terminal side mean?

: a straight line that has been rotated around a point on another line to form an angle measured in a clockwise or counterclockwise direction — compare initial side.

## What are the negative and positive Coterminal angles of 240 degrees?

Add 360° to find a positive coterminal angle. Subtract 360° to find a negative coterminal angle. Angles that measure 240° and –480° are coterminal with a –120° angle.

## How do you find a positive Coterminal angle?

To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians . Example 1: Find a positive and a negative angle coterminal with a 55° angle.

## What are the sides of an angle?

In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
