## Angle bisector

### An angle bisector is a line or ray that divides an angle into two equal parts

An angle bisector is a line or ray that divides an angle into two equal parts. The point where the angle bisector meets the angle is known as the vertex.

To construct an angle bisector, you can follow these steps:

1. Draw the angle: Use a ruler and a protractor to draw the angle. Make sure the sides of the angle extend long enough to intersect with the angle bisector.

2. Place the compass at the vertex of the angle: Open the compass to any width and place the sharp end at the vertex of the angle.

3. Draw arcs: Keeping the compass width the same, draw an arc on each side of the angle. The arcs should intersect the two sides of the angle.

4. Connect the intersection points: Use a ruler to draw a straight line that connects the two intersection points from the previous step. This line is the angle bisector.

The angle bisector divides the angle into two congruent angles, meaning both parts of the angle will have the same measure.

It’s important to note that an angle bisector can also be found algebraically using the properties of angles and equations. By setting up equations and solving for variables, you can find the angle bisector’s slope, equation, or other properties. This method can be used in more advanced mathematics classes.
