Constructions

Front

What is a perpendicular bisector?

Back

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

Front

What is the purpose of a compass in constructions?

Back

To draw arcs and circles, and to measure distances.

Front

What is the definition of a line segment?

Back

A part of a line that is bounded by two distinct endpoints.

Front

What does it mean for two lines to be parallel?

Back

Two lines that run in the same direction and never intersect.

Front

What is an angle bisector?

Back

A line that divides an angle into two equal angles.

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but different sizes.

Front

How do you construct a perpendicular bisector of a line segment?

Back

1. Place the compass point on one endpoint and draw an arc above and below the line. 2. Without changing the compass width, repeat from the other endpoint. 3. Draw a line through the intersection points of the arcs.

Front

What is the definition of altitude in geometry?

Back

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

Front

What is the significance of using a straightedge in constructions?

Back

To draw straight lines and measure distances accurately.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines that intersect at a right angle (90 degrees).
