Parallelograms, Slope/Distance Review and Polygons

Front

What is a parallelogram?

Back

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

Front

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is a heptagon?

Back

A heptagon is a polygon with seven sides.

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles is (n - 2) × 180 degrees.

Front

What is the relationship between the opposite angles of a parallelogram?

Back

The opposite angles of a parallelogram are equal.
