Geometry Unit 3 Review

Front

What is the equation of a line with a slope of 3 that passes through the point (5, 8)?

Back

y = 3x - 7

Front

What are alternate interior angles when two lines are parallel?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

Identify the alternate interior angles given lines c and d are parallel.

Back

∠8, ∠13

Front

What are consecutive interior angles when two lines are parallel?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

Identify the consecutive interior angles given lines c and d are parallel.

Back

∠4, ∠11

Front

What condition must be met for two lines to be parallel?

Back

They must have the same slope.

Front

If m∠12 = 85°, what is m∠10 if lines c and d are parallel?

Back

m∠10 = 95°

Front

What is the slope-intercept form of a line?

Back

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

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the definition of parallel lines?

Back

Lines that never intersect and have the same slope.
