Front

What is angle measure?

Back

The size of an angle, typically measured in degrees.

Front

What are complements and supplements?

Back

Complements are two angles that add up to 90 degrees; supplements add up to 180 degrees.

Front

What are polygons?

Back

A polygon is a closed figure with three or more sides.

Front

What are parallel line angle relationships?

Back

Angles formed when a transversal crosses parallel lines.

Front

What is congruency?

Back

Two figures are congruent if they have the same shape and size.

Front

What is coordinate geometry?

Back

The study of geometric figures using a coordinate system.

Front

What is slope?

Back

The measure of the steepness of a line, calculated as rise over run.

Front

What are equations of lines?

Back

Mathematical expressions that describe the relationship between x and y coordinates.

Front

What are intercepts?

Back

Points where a line crosses the x-axis or y-axis.

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.
