If you bisect a 30 degree angle, you end up with two 15 degree angles.
15 degrees. A bisected 60 degree angle makes 2 30 degree angles by definition of an angle bisector, then a 30 degree angle makes 2 15 degree angles by definition of an angle bisector.
30 degree angle
Yes.
a 60 degree angle is twice the size of a 30 degree angle.
The beam of light would be reflected at a 30 degree angle from the normal to the mirror. This means the angle of reflection would also be 30 degrees.
30 degrees
The takeoff for a 30 degree angle will depend with the offset angle.
A right angle
Yes and they are both acute angles
a 60-degree angle
The complement to a 60 degree angle would be 30. The ratio then would be 2.
A 180-degree angle can be divided into six 30-degree angles. This is because 180 divided by 30 equals 6, meaning that six 30-degree angles can fit within a 180-degree angle.
