Geometry Concepts - Chapter 4 Review

Front

What are Consecutive Interior Angles?

Back

Consecutive Interior Angles are pairs of angles that lie on the same side of a transversal and between two parallel lines. They are supplementary, meaning their measures add up to 180 degrees.

Front

How do you find the slope of a line?

Back

The slope of a line is calculated as the change in y divided by the change in x (rise/run). If the line is vertical, the slope is undefined.

Front

What is the equation to find the value of X in angle relationships?

Back

The equation 8X - 17 = 5X + 19 can be used to find the value of X when dealing with angle relationships.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis. For the equation y = 4x - 10, the y-intercept is -10.

Front

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie on opposite sides of a transversal and outside the two parallel lines. They are equal when the lines are parallel.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between 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 when the lines are parallel.

Front

How do you determine if two lines are parallel using angles?

Back

If the corresponding angles or alternate interior angles are equal, then the two lines are parallel.

Front

What is the formula for the slope-intercept form of a line?

Back

The slope-intercept form of a line is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean if the slope of a line is 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.
