Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What is the formula to find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the image of the point (3, 2) after reflection across the x-axis?

Back

The image is (3, -2).

Front

What is the angle pair name for angles that are on the same side of the transversal and inside the two parallel lines?

Back

These angles are called same side interior angles.

Front

If m∠8 = 7x - 12 and m∠1 = 4x + 6, how do you find x?

Back

Set the two expressions equal to each other: 7x - 12 = 4x + 6, then solve for x.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What is the reflection of the point (-2, 3) across the x-axis?

Back

The reflection is (-2, -3).

Front

How do you calculate the slope of a line that passes through the points (6, 7) and (4, 2)?

Back

Using the slope formula: m = (2 - 7) / (4 - 6) = 5/2.

Front

What is the definition of alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What is the value of x if 5x + 3 = 18?

Back

x = 3.
