What is the angle relationship when two lines are cut by a transversal and the angles on the same side of the transversal are supplementary?

Back

Same-side interior angles.

Front

What is true about the slopes of perpendicular lines?

Back

Perpendicular lines have negative reciprocal slopes.

Front

What is the definition of a transversal?

Back

A line that intersects two or more lines in a plane.

Front

Identify the angle relationship: Two angles that are on opposite sides of the transversal and inside the two lines.

Back

Alternate interior angles.
