Usually by means of a protractor.
The bisector of an angle is the ray that divides the angle into two smaller angles of equal measure.
A bisector splits the angle into to equal halves.
They are half the original angle, whatever that was.
To name an angle bisector, you typically use the vertex of the angle and the points where the bisector intersects the sides of the angle. For example, if you have an angle formed by points A, B, and C, where B is the vertex, and the bisector intersects the sides at points D and E, you can name the angle bisector as segment BD or segment BE, depending on which side you refer to. It’s also common to denote the angle bisector with the symbol for bisector, such as ( \overline{BD} ) or ( \overline{BE} ).

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.
The bisector of an angle is the ray that divides the angle into two smaller angles of equal measure.
A bisector splits the angle into to equal halves.
The answer to that is a bisector. The two angles formed by this has the same angle.
45 degree angle
Not exactly.A ray that divides an angle into two angles of equal measure is called an angle bisector.
They are half the original angle, whatever that was.
4 angles are formed
An angle bisector of a 90-degree angle is a line or ray that divides the 90-degree angle into two equal angles of 45 degrees each. It is a line that passes through the vertex of the angle and divides it into two congruent angles. In a right triangle, the angle bisector of the right angle will also bisect the opposite side, creating two smaller right triangles.
