Chapter 3 Test Review

Front

What is the slope of a line that is perpendicular to the line represented by the equation y = -\frac{1}{3}x + 5?

Back

The slope of a line that is perpendicular to another line is the negative reciprocal of the original line's slope. Therefore, the slope is 3.

Front

Write the equation of a line in slope-intercept form that is perpendicular to y = -\frac{1}{3}x + 5 and passes through the point (6,4).

Back

The equation is y = 3x - 14.

Front

What type of angle pair are formed when two lines are crossed by a transversal?

Back

The angle pairs can be corresponding, alternate interior, same side interior, or same side exterior.

Front

Define corresponding angles.

Back

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

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between parallel lines and corresponding angles?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal.

Front

Identify the angle pair relationship: ∠1 and ∠2 are formed by two parallel lines cut by a transversal and are in the same position relative to the lines.

Back

Corresponding Angles.

Front

What is the classification of angles ∠7 and ∠10 if they are not equal and do not fit any other specific angle pair relationship?

Back

None.

Front

What is the definition of vertical angles?

Back

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

Front

How can you determine if two lines are parallel based on their slopes?

Back

Two lines are parallel if they have the same slope.
