What is the equation to solve for x in a parallelogram when given 14x + 2 + 80 = 180?

Back

The equation is 14x + 2 + 80 = 180.

Front

What is always true about a horizontal line in relation to a vertical line?

Back

A horizontal line is always perpendicular to a vertical line.

Front

What can be said about two lines whose slopes are negative reciprocals?

Back

They are perpendicular.

Front

Which tools are used to bisect an angle in a mathematical construction?

Back

A compass and a straightedge.

Front

What are the new coordinates of point J(1, 0) after translation by (x, y) -> (x+5, y-4)?

Back

The new coordinates are (6, -4).

Front

Define a parallelogram.

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is the definition of perpendicular lines?

Back

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

Front

What is the slope of a line that is parallel to another line?

Back

The slope of a parallel line is equal to the slope of the original line.

Front

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

Back

Corresponding angles are equal.

Front

What is the formula for 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).
