Angle Relationships

100

A line that intersects a pair of lines at different points is called this.

What is a transversal?

200

Two angles that are on opposite sides of a transversal and lie outside the two lines that the transversal intersects are called this

What are alternate exterior angles?

300

A pair of angles that are created by two lines and a transversal that lie in between the two lines are called this.

What are interior angles?

400

Two corresponding angles are __________ congruent when two lines are cut by a transversal.

What is sometimes?

500

Two angles (not vertical or adjacent) must share this in order to have a direct angle relationship.

What is a transversal?

Parallel Lines and Angle Relationships

100

Two parallel lines are cut by a transversal. This can be said for a pair of consecutive interior angles.

What is supplementary?

200

Two alternate exterior angles are created by two parallel lines and a transversal. One angle is 37^o. The other must be this.

What is 37^o?

300

A pair of alternate interior angles are created by a set of parallel lines and a transversal. Angle 1 has a measure of (15x + 10)^o and Angle 2 has a measure of (20x - 30)^o. The measure of each angle must be this.

What is 130^o?

400

Two streets are parallel and a 3rd street intersects one of the parallel streets at a right angle. The intersection with the 3rd street and other parallel line must be this.

What is perpendicular?

500

In order to form a parallelogram (4 sided figure with opposite sides parallel), this must be true about opposite angles.

What is they must be congruent?

Proving Lines Parallel

100

Alternate interior angles must be this in order to make lines parallel.

What is congruent?

200

In order for two lines to be parallel that have a transversal intersecting them, consecutive interior angles must be this.

What is supplementary?

300

A pair of consecutive interior angles have values 3x and 9x. Find the value of x to prove the lines parallel.

What is x=15?

400

A pair of corresponding angles are used to prove two lines parallel. One angle has a measure of (5x - 14)^o and the other has a measure of (2x + 25)^o. The measure of each angle must be this.

What is 51^o?

500

Three lines are cut by a transversal. Angle 1 and 2 are alternate exterior angles. Angle 2 and 3 are corresponding angles.  If the angles are listed from top to bottom (Angle 1 on line 1, angle 2 on line 2, angle 3 on line 3) and you need to prove lines parallel, angle 1 and angle 3 must be this.

What are congruent?

Slope and Equations of Lines

100

The slope of a line can be described as this.

What is rise over run?

200

Any line crosses the y-axis at this point, unless it's undefined.

What is the y-intercept?

300

This equation of a line has a slope of 4 and travels through point (3,8).

What is y = 4x - 4?

400

Calculate the slope of the line that passes through (-2,6) and (4,3).

What is -1/2?

500

Write the equation of the line that passes through points (-2,6) and (4,3).

What is y = -1/2x + 5?

Equations of Parallel and Perpendicular Lines

100

Parallel lines have these kinds of slope.

What are same slopes?

200

Perpendicular lines have these kinds of slope.

What are opposite reciprocal slopes?

300

The slope of a line is -2/3. In order for a second line to be perpendicular to the first, its slope must be this.

What is 3/2?

400

Given the equation y = 1/2x - 4, a line parallel to this one that travels through (-2,8) has this equation.

What is y = 1/2x + 9?

500
