Geometry Chapter 3 Parallel and Perpendicular Lines

Front

What is the slope between the two points (1,4) and (3,9)?

Back

Front

Parallel lines have what kind of slope?

Back

Parallel lines have equal slopes.

Front

What type of angles are 1 and 8 when two parallel lines are cut by a transversal?

Back

Angles 1 and 8 are Alternate Exterior angles.

Front

What type of angles are 4 and 5 when two parallel lines are cut by a transversal?

Back

Angles 4 and 5 are Alternate Interior angles.

Front

What is the equation of a line parallel to y=-4x + 6 and passes through (2, -1)?

Back

The equation is y=-4x+7.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and have the same slope.

Front

What is the definition of perpendicular lines?

Back

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

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

If two lines have slopes of 2 and -rac{1}{2}, are they parallel, perpendicular, or neither?

Back

They are perpendicular because their slopes are opposite reciprocals.

Front

What are corresponding angles?

Back

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