Perpendicular Bisector

The perpendicular bisector is a line or a line segment that intersects another line segment at a right angle and divides it into two equal parts

The perpendicular bisector is a line or a line segment that intersects another line segment at a right angle and divides it into two equal parts. In other words, it is a line that cuts another line segment exactly in half and forms a right angle (90 degrees) with it.

To construct the perpendicular bisector of a line segment, you can follow these steps:

1. Draw the line segment.
2. With your compass, place the point of the compass on one endpoint of the line segment and adjust the compass width to slightly more than half the length of the line segment.
3. Using the compass, draw arcs on each side of the line segment to create two points where the arcs intersect the line segment.
4. Without changing the compass width, place the compass point on the other endpoint of the line segment and draw two more arcs, intersecting the line segment in the same way as before.
5. Connect the two points where the arcs intersect, and this line will be the perpendicular bisector of the line segment.

The perpendicular bisector has several properties:

1. It is equidistant from the two endpoints of the line segment.
2. It divides the line segment into two equal lengths.
3. It forms a right angle (90 degrees) with the line segment it bisects.

The perpendicular bisector is commonly used in geometry, especially in constructions and proofs. It helps in determining the midpoint of a line segment and finding the line of symmetry for various shapes.
