What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What is the Converse of the Consecutive Interior Angles Theorem?

Back

If two lines are cut by a transversal and the consecutive interior angles are supplementary, then the lines are parallel.

Front

What is the relationship of alternate exterior angles when two lines are parallel?

Back

When two parallel lines are cut by a transversal, the alternate exterior angles are congruent.

Front

What is point-slope form of a linear equation?

Back

The point-slope form is given by the equation y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is a point on the line.

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), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

Front

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

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 are transversal lines?

Back

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

Front

What is the relationship between corresponding angles when two lines are parallel?

Back

When two parallel lines are cut by a transversal, the corresponding angles are congruent.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How can you determine if two lines are parallel using angle relationships?

Back

If alternate interior angles are congruent or if corresponding angles are congruent, then the lines are parallel.
