Front

Define perpendicular lines.

Back

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

Front

Define parallel lines.

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.
