What is the relationship between parallel lines and angles formed by a transversal?

Back

When a transversal crosses parallel lines, corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

What does it mean for two line segments to be congruent?

Back

Two line segments are congruent if they have the same length.

Front

What is the definition of a rigid motion in geometry?

Back

A rigid motion is a transformation that preserves distance and angle measures, meaning the size and shape of the figure remain unchanged.

Front

If two lines have the same slope, what can be said about their relationship?

Back

If two lines have the same slope, they are parallel.

Front

What is the translation rule for moving a point 2 units to the right and 6 units down?

Back

The translation rule is (x + 2, y - 6).

Front

What is the Angle-Side-Angle (ASA) congruence postulate?

Back

The ASA postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines never intersect and have the same slope, while perpendicular lines intersect at a right angle (90 degrees) and have slopes that are negative reciprocals.

Front

What does the Side-Angle-Side (SAS) congruence postulate state?

Back

The SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the definition of a transversal in geometry?

Back

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