Geometry Constructions

Front

What is the perpendicular bisector of a line segment?

Back

A line that divides a line segment into two equal parts at a 90-degree angle.

Front

What does the term 'bisect' mean?

Back

To cut something into two congruent pieces or in half.

Front

What is an angle bisector?

Back

A line that divides an angle into two equal angles.

Front

What is a perpendicular line?

Back

A line that intersects another line at a 90-degree angle.

Front

What is the construction for finding the midpoint of a line segment?

Back

Draw two circles with the same radius from each endpoint of the segment, then connect the intersection points.

Front

What is the difference between a line and a line segment?

Back

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

Front

What is an altitude in geometry?

Back

A perpendicular segment from a vertex to the line containing the opposite side.

Front

How do you construct a perpendicular bisector?

Back

Use a compass to draw arcs from both endpoints of the segment, then connect the intersection points.

Front

What is the significance of the midpoint in geometry?

Back

It is the point that divides a segment into two equal parts.

Front

What is a ray in geometry?

Back

A part of a line that starts at a point and extends infinitely in one direction.
