HGeom - Chapter 3 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 is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you find the slope of a line given two points?

Back

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

Front

What is the slope of a line that is parallel to a line with a slope of 3/4?

Back

The slope of a line parallel to a line with slope 3/4 is also 3/4.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

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

Back

When two parallel lines are cut by a transversal, several angle relationships are formed, including corresponding angles, alternate interior angles, and alternate exterior angles.

Front

How do you determine if two angles are supplementary?

Back

To determine if two angles are supplementary, add their measures together; if the sum is 180 degrees, they are supplementary.

Front

What is the formula for calculating the slope of a line?

Back

The formula for calculating the slope (m) of a line is m = (y2 - y1) / (x2 - x1).

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

What is the value of x if the equation is set up as x + 10 = 29.5?

Back

The value of x is 19.5.
