the angle with 60 degrees has a reference angle of 60 degrees?
sorry posted twice
A reference angle is defined as:
"A reference angle for an angle is the positive acute angle made by the terminal side of angle and the x-axis."
by which we conclude that all angles in the first quadrant equal their reference angles.
No, the angle with 60 degrees does not have a reference angle of 60 degrees. The reference angle is the acute angle formed between the terminal side of an angle and the x-axis on the coordinate plane.
To find the reference angle, you can follow these steps:
1. Determine the quadrant in which the angle lies. In this case, a 60-degree angle is in the first quadrant.
2. Subtract the given angle from 90 degrees (for angles in the first or second quadrant) or 180 degrees (for angles in the third or fourth quadrant). In the case of a 60-degree angle in the first quadrant, subtract 60 degrees from 90 degrees.
3. The result is the reference angle. In this case, the reference angle for a 60-degree angle in the first quadrant is 30 degrees.
So, the angle with 60 degrees has a reference angle of 30 degrees, not 60 degrees.
