What is the reference angle for -140 degrees?
in order to find the reference angle, an angle less than or equal to 90 degrees formed by the x-axis and the terminal side of an angle, one needs to first find what quadrant on the coordinate plane the angle belongs to. The negative (-) sign in -140 refers to the direction 360 degree turn begins at (and therefore the quadrant it begins at). Instead of taking the regular backwards "C", counterclockwise direction, the turn begins clockwise. To convert it, simply add 360 degrees, to get 220 degrees, an angle in the third quadrant. These are the guidelines to follow when finding reference angles: If angle, A, is in first quadrant then the reference angle will be itself as it is already 90 degrees or under. If angle, A, is in second quadrant then the reference angle will be 180 - A . If angle, A, is in third quadrant then the reference angle will be A - 180 . If angle, A, is in fourth quadrant then the reference angle will be 360 - A " These subtractions are all in reference to the nearest angle of a quadrant and are in degrees. Being in the third quadrant, take the angle, A, and subtract 180 from it to get: 220 - 180 = 40 Thus, the reference angle for -140 degrees is 40 degrees. Follow the same directions for other angles, first determining whether the angle needs to be converted into a positive value (counterclockwise), then locate the quadrant and use the rules above for the specific angle(s) being looked at and asked for.
What is angle in a quadrant?
An angle in a quadrant refers to an angle formed by a ray that originates from the origin of a coordinate plane and lies within one of the four quadrants. Each quadrant is defined by the x-axis and y-axis, and angles in a quadrant are measured in a counterclockwise direction from the positive x-axis. The measure of an angle in a quadrant typically ranges from 0 degrees to 90 degrees.
What do you call a quarter of a circle?
A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
What is the angle of rotation of a circle?
360 degrees.
If an angle is inscribed in a circle what is the measure of the angle?
6Improved Answer:-There are 360 degrees around a circle and any part of it is an arc.
Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
What is the measure of an angle whose cosine 0.5?
The measure of an angle whose cosine is 0.5 is 60 degrees (or (\frac{\pi}{3}) radians) in the first quadrant. Additionally, in the context of the unit circle, the angle can also be 300 degrees (or (\frac{5\pi}{3}) radians) in the fourth quadrant.
What quadrant does angle - 980 degrees lie in?
The answer is 3rd quadrant because 980 degree -720 degree =260 degrees so the 3rd quadrant is 180 degrees to 270 degrees
What is the difference between quadrant and azimuthal notation?
When calculating a bearing, azimuthal notation refers to the angle of the bearing from North, measured clockwise. Quadrant notation takes the bearing from north or south with a change to west or east. For example, Quadrant notation: SE = Azimuth notation of 135 degrees.
In which quadrant does an angle of 360 degrees lie?

In what quadrant is 361 degree?
In a circle ,there are 4 quadrants,each quadrant have 90 degree angle, therefore 4x90=360 degree so 361 degree angle will be in first quadrant.
What are the 3 benchmark angle measures found in quadrant 2?
In quadrant II, the three benchmark angle measures are 90 degrees, 120 degrees, and 135 degrees. The angle of 90 degrees corresponds to the positive y-axis, while 120 degrees and 135 degrees are commonly referenced angles where sine values are positive and cosine values are negative. These angles are often used in trigonometric calculations involving the unit circle.
What is a 264 degree angle?
A 264-degree angle is an obtuse angle that measures 264 degrees, which means it is greater than 180 degrees but less than 360 degrees. In a full circle, which measures 360 degrees, an angle of 264 degrees can also be described as being in the third quadrant. This angle can be visualized as rotating 264 degrees counterclockwise from the positive x-axis.
What is angle in a quadrant?
An angle in a quadrant refers to an angle formed by a ray that originates from the origin of a coordinate plane and lies within one of the four quadrants. Each quadrant is defined by the x-axis and y-axis, and angles in a quadrant are measured in a counterclockwise direction from the positive x-axis. The measure of an angle in a quadrant typically ranges from 0 degrees to 90 degrees.
What quadrant is -182 degrees?
To determine the quadrant of -182 degrees, first convert it to a positive angle by adding 360 degrees, resulting in 178 degrees. Since 178 degrees falls between 180 and 360 degrees, it is located in the second quadrant. Therefore, -182 degrees is in the second quadrant.
How do we measure an angle?
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
