Geometry: Recognizing Basic Constructions

Front

What is the definition of a perpendicular bisector?

Back

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

What is the purpose of using a compass in geometric constructions?

Back

A compass is used to draw arcs and circles, and to measure distances between points.

What does it mean to 'copy an angle' in geometry?

Back

Copying an angle involves creating a new angle that is congruent to a given angle using a compass and straightedge.

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

Back

To construct a perpendicular line to a point not on the line, place the compass point on the given point, draw an arc that intersects the line, then use those intersection points to create a perpendicular line.

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

What is the significance of the midpoint in segment constructions?

Back

The midpoint is the point that divides a segment into two equal lengths, crucial for constructions like perpendicular bisectors.

What is the construction method for creating a parallel line to a point not on the line?

Back

To create a parallel line, use a straightedge to draw a line through the given point that maintains the same angle as the original line.

Front

What is the role of a straightedge in geometric constructions?

Back

A straightedge is used to draw straight lines and to connect points in geometric constructions.

What is the definition of a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.
