Yes. Quadrantal angles have reference angles of either 0 degrees (e.g. 0 degrees and 180 degrees) or 90 degrees (e.g. 90 degrees and 270 degrees).

What is the measure of quadrantal angle?
A quadrantal angle is one whose initial arm is the positive x-axis and whose terminal arm is on the y-axis or the y-axis.In other words, it is k(90 degrees), k is an integer.(in radians: k(pi)/2)
What is the reference angle for an angle with a measure of 331degree?
360-331=2929 degrees is your reference angle. Remember your signs, though.
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 a reference angle?
A main angle of refrence.
What is the angle reference for a right angle?
90 degrees
Find value of trigonometric functions of quadrantal angle?

What is the angle when the terminal side of an angle in standard position lies along one of the axes?
Quadrantal angle
What is a quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.

Is 38 pi divided by 4 radians a quadrantal angle?
9.5
What is a non quadrantal angle?
A quadrantal angle is one that in 0 degrees, 90 degrees, 180 degrees, 270 degrees or 360 degrees (the last one being the same as 0 degrees). These are the angles formed by the coordinate axes with the positive direction of the x-axis. All other angles (in the range 0 to 360 degrees) are non-quadrantal

What is the reference angle for an angle with the measure of 175 degrees?
The reference angle for an angle with the measure of 175 degrees is 5 degrees
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.
