What is the definion of bisect?

"Bisect" means to divide something into two equal parts. It's often used in the context of geometry, but can be applied to other situations as well.

Here's how it's used in different contexts:

Geometry:

* Bisect a line segment: Divide the line segment into two parts of equal length. This is done by finding the midpoint.

* Bisect an angle: Divide the angle into two equal angles. This is done by drawing a line that cuts the angle in half.

Other contexts:

* Bisect a time period: Split a period of time in half. For example, you could bisect the month of June by dividing it into two equal parts.

* Bisect a population: Divide a group of people into two roughly equal groups.

In general, "bisect" means to divide something in half, whether that's a line, an angle, a time period, or anything else.
