Front

What is an angle bisector?

Back

A ray that divides an angle into two congruent angles.

Front

What is a perpendicular bisector?

Back

Front

What is the construction for duplicating an angle called?

Back

Copying an angle.

Front

What is a line segment?

Back

A part of a line that has two endpoints.

Front

What does it mean for angles to be congruent?

Back

Angles that have the same measure.

Front

What is the purpose of geometric constructions?

Back

To create precise figures using only a compass and straightedge.

Front

What is the difference between an angle bisector and a perpendicular bisector?

Back

An angle bisector divides an angle, while a perpendicular bisector divides a segment at a right angle.

Front

How do you construct a perpendicular bisector of a segment?

Back

By using a compass to draw arcs from both endpoints and connecting the intersection points.

Front

What is the definition of midpoint?

Back

The point that divides a segment into two equal parts.
