Ch 3 Review

Front

What does it mean for two planes to be parallel?

Back

Two planes are parallel if they do not intersect and are equidistant from each other at all points.

Front

What is a bisector in geometry?

Back

A bisector is a line or ray that divides an angle or a segment into two equal parts.

Front

How do you calculate the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What are parallel lines?

Back

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

Front

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

Back

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

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel; they exist in different planes.

Front

If two lines are parallel, what can be said about the angles formed when a transversal crosses them?

Back

The angles formed are either equal (corresponding angles) or supplementary (consecutive interior angles).

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables.

Front

How do you determine if two lines are parallel using their slopes?

Back

Two lines are parallel if they have the same slope.

Front

What is the formula for finding the y-coordinate of a point on a line given its slope?

Back

Using the point-slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
