GEOMETRY: Chapter 3 REVIEW

Front

What is the slope of a line perpendicular to y = mx + b?

Back

The slope of a line perpendicular to y = mx + b is -1/m.

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is a transversal line?

Back

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

Front

What is the relationship between corresponding angles when a transversal crosses parallel lines?

Back

Corresponding angles are equal when a transversal crosses parallel lines.

Front

What is the measure of angles that are supplementary?

Back

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

Front

What is the measure of angles that are complementary?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the slope of the line y = 2x + 4?

Back

The slope of the line y = 2x + 4 is 2.

Front

If a line has a slope of -1/2, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to a line with slope -1/2 is 2.

Front

What is the y-intercept of the line y = 3x - 5?

Back

The y-intercept of the line y = 3x - 5 is -5.
