What is a trapezoid?

Back

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

Front

How do you find the slope of a line?

Back

The slope of a line is calculated as the change in y divided by the change in x (rise/run).

Front

What is the formula for slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What is the distance formula?

Back

The distance between two points (x1, y1) and (x2, y2) is given by: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula?

Back

The midpoint between two points (x1, y1) and (x2, y2) is: Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What defines a quadrilateral?

Back

A quadrilateral is a polygon with four sides and four vertices.

Front

What are the properties of a rectangle?

Back

A rectangle is a quadrilateral with opposite sides equal and all angles equal to 90 degrees.

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length.

Front

How can you identify a square?

Back

A square is a quadrilateral that has all sides equal and all angles equal to 90 degrees.

Front

What is the significance of parallel lines in coordinate geometry?

Back

Parallel lines have the same slope and never intersect.
