Bisect
In geometry, to bisect something means to divide it into two equal parts. This concept is commonly used when bisecting angles, segments, or other geometric shapes.
Bisecting a Segment
To bisect a segment means to divide it into two equal parts. This can be done by finding the midpoint of the segment, which is the point that divides the segment into two equal parts.
The midpoint of a segment with endpoints (x1, y1) and (x2, y2) can be found using the midpoint formula:
\[ \left(\frac{x1 + x2}{2}, \frac{y1 + y2}{2}\right) \]Bisecting an Angle
To bisect an angle means to divide it into two equal angles. This can be done using a compass and straightedge, or by using geometric theorems and properties.
When an angle is bisected, it is divided into two smaller angles of equal measure. The angle bisector is the line or ray that divides the angle into two equal parts.
Study Guide:
