Did you know?
Web14 dec. 2024 · Example 1: Find the reference angle for 150 degrees. 180 - 150 = 30 degrees. Therefore, the reference angle is 30 degrees. If the terminal side of the angle is in the third quadrant, we take 180 ... WebCalculating Reference Angles If an angle's terminal side on the x x -axis, the reference angle is 0. If an angle's terminal side is on the y y -axis, the reference angle is \frac {\pi} {2} 2π (that is, 90^\circ 90∘ ). Otherwise, to find the reference angle: If the angle is not in the usual range of [0, 2\pi) [0,2π) or
WebReference angle° = angle Terminal side is in the second quadrant When the terminal side is in the second quadrant (angles from 90° to 180° or from π/2 to π), our reference angle is 180° minus our given angle. So, you can use this formula. Reference angle° = 180 - angle For example: The reference angle of 125 is 180 - 125 = 55°. Webangle = float (input ("Enter angle (deg) to calculate reference angle for : ")) angle = angle%180 if angle > 90 : angle = 180 - angle print ("Reference Angle = ",angle) Share Improve this answer Follow edited Mar 19, 2024 at 20:45 answered Mar 19, 2024 at 20:28 Alistair 589 3 11 Add a comment Not the answer you're looking for?
Web3 mrt. 2024 · To calculate the angles inside a polygon, first count the number of interior angles. A polygon has the same number of interior angles as sides. For example, a triangle always has 3 angles, while a square or rectangle always has 4, and so on. WebReference angle° = angle Terminal side is in the second quadrant When the terminal side is in the second quadrant (angles from 90° to 180° or from π/2 to π), our reference angle is 180° minus our given angle.
