π to 3π/2 — Third quadrant, so reference angle = angle − π; and 3π/2 to 2π — Fourth quadrant, so reference angle = 2π − angle. As you can see, this procedure is similar to the one above for degrees. As an example, let's consider the angle of 28π/9 radians. ...
解析 Find an angle that is positive, less than ( 360°), and coterminal with ( -45°).( 315°)Since the angle( 315°) is in the fourth quadrant, subtract ( 315°) from ( 360°).( 360°-315°)Subtract ( 315) from ( 360).( 45°)...
Use our reference angle calculator to find the reference angle for any angle in degrees or radians. Plus, learn the reference angle formulas.
We can find the reference angle of an angle in the first quadrant by following these steps: Find the degree of the angle in the question. If the angle is in between 0 degree sand 90 degrees, then it lies in the first quadrant, and the reference angle will be equal to the measure of...

The angle must always lie between 0 and 180 degrees. Larger or smaller angles may be entered, but they will be taken modulo 180 degrees. The sign of the angle is ignored. When two lines intersect, four angles are formed. These angles form two equal pairs. For example, the pictured lines...
Angle Directed is a refinement layout algorithm that processes diagram edges. It applies to any type of diagram. This layout algorithm progressively moves the diagram's edges in specified alignment directions. For each diagram edge, this layout notes its current direction, searches for the nearest...
