H Geom Ch 3 Review for Test

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

Identify the slope of the line: y = -1/4 x - 5.

Back

The slope is -1/4.

Front

Identify the slope of the line: y = 4x + 2.

Back

The slope is 4.

Front

What type of angle pair are alternate interior angles?

Back

Alternate interior angles are angles that lie between two lines and on opposite sides of a transversal.

Front

What type of angle pair are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect.

Front

What is the equation of a line parallel to y = -6x + 3 that passes through (-1, 4)?

Back

y = -6x + 4.

Front

What is the equation of a line perpendicular to y = -6x + 3 that passes through (-1, 4)?

Back

y = 1/6x + 25/6.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.
