Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, regardless of how far they are extended.

Front

What is the value of x that makes line m parallel to line n if the angles formed are 120 degrees and x degrees?

Back

x must be 60 degrees, as parallel lines create alternate interior angles that are equal.

Front

What is the definition of a transversal line?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

Front

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

Back

Alternate interior angles are equal when two lines are parallel.

Front

How do you solve for y in a linear equation?

Back

To solve for y, isolate y on one side of the equation using algebraic operations such as addition, subtraction, multiplication, or division.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of supplementary angles?

Back

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

Front

What is the definition of complementary angles?

Back

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

Front

What is the formula for the slope of a line?

Back

The slope (m) of a line is calculated as m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
