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.

Can you find the reference angle of a quadrantal angle?
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 relationship between the measure of an angle and the reflex measure of the angle?
they both measure the angle in degrees

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 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.

Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
How do you measure a angle?
you can measure a angle with a protracte.

The measure of an angle is fourteen times the measure of a complementary angle. What is the measure of each angle?
The measure of an acute angle is half the measure of an obtuse angle.What is the measure of an obtuse angle?
The measure of the obtuse angle would then be double that of the acute angle.
