How do you construct a perpendicular bisector?

Back

To construct a perpendicular bisector, you need to find the midpoint of a line segment and draw a line that is perpendicular to the segment at that midpoint.

What is the process to copy an angle?

Back

To copy an angle, place the vertex of the angle at a point, then use a compass to replicate the angle's arms.

How do you construct a perpendicular line through a point not on the line?

Back

To construct a perpendicular line through a point not on the line, use a compass to create arcs from both the line and the point, then connect the intersection points.

What is the significance of the midpoint in constructions?

Back

The midpoint is crucial in constructions like perpendicular bisectors, as it helps ensure that the two segments created are equal in length.

What tools are commonly used in geometric constructions?

Back

Common tools include a compass, straightedge (ruler), and protractor.

Front

What is the difference between a segment and a line?

Back

A segment has two endpoints and a finite length, while a line extends infinitely in both directions.
