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).
A quadrantal triangle is a type of triangle in which one of its angles measures exactly 90 degrees, while the other two angles are each 45 degrees. This specific configuration results in an isosceles right triangle, where the two legs are of equal length, and the hypotenuse is the longest side. Quadrantal triangles are often used in trigonometry and geometry due to their unique properties and relationships between their angles and side lengths.
There is no single formula: there are several, depending on what information you have and what you wish to know.
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)
It's an equilateral triangle whose legs are all 90-degree arcs. Here's a quadrantal triangle on the earth: -- Start at the north Pole. -- Draw the first side, down along the north 1/2 of the Prime Meridian to the equator. -- Draw the second side westward along the equator, to 90 degrees west longitude. -- Draw the third side straight north, back up to the north Pole. Each side of the triangle is 90 degrees, each interior angle is also 90 degrees, and the sum of its interior angles is 270 degrees. Pretty weird.

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

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.

30-60-90 and 45-45-90 triangles are not particularly useful for quadrantal angles because these angles (0°, 90°, 180°, and 270°) correspond to specific points on the unit circle where the sine or cosine values are straightforward (0, 1, -1). These points do not require the detailed relationships defined by the special triangles, as the values can be directly derived from the coordinates of the circle. Therefore, the unique properties of 30-60-90 and 45-45-90 triangles are unnecessary for determining the trigonometric values at these specific angles.
