Unit 2 Parallel and Perpendicular Lines Test Study

Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the relationship between two angles that form a straight line?

Back

Linear Pairs

Front

How do you find the third angle of a triangle if two angles are known?

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you convert the equation 5x - 3y = -9 into slope-intercept form?

Back

Rearrange to get y = (5/3)x + 3.

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

What is the definition of parallel lines?

Back

Lines that never intersect and have the same slope.

Front

What is the definition of perpendicular lines?

Back

Lines that intersect at a right angle (90 degrees).

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.
