Coordinate Geometry

Front

What is 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).

Front

Define a parallelogram.

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length.

Front

What is the definition of a rectangle?

Back

A rectangle is a parallelogram with four right angles.

Front

What is a rhombus?

Back

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

Front

Define a square.

Back

A square is a rectangle with all four sides of equal length.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

The distance (d) is calculated as d = √((x2 - x1)² + (y2 - y1)²).

Front

What are the coordinates of the midpoint between two points (x1, y1) and (x2, y2)?

Back

The midpoint (M) is given by M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the formula for the area of a rectangle?

Back

The area (A) is calculated as A = length × width.

Front

What is the formula for the area of a parallelogram?

Back
