Polygons on the Coordinate Plane

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (X,Y).

Front

How do you calculate the perimeter of a square?

Back

The perimeter of a square is calculated by adding the lengths of all four sides, or using the formula P = 4s, where s is the side length.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula A = length × width.

Front

What does the Y-axis represent in a coordinate plane?

Back

The Y-axis represents the vertical line in a coordinate plane, where the X-coordinate is 0.

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 find the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula A = base × height.

Front

What are the coordinates of a point?

Back

Coordinates of a point are a pair of numbers (X,Y) that define its position on a coordinate plane.

Front

What is the difference between a square and a rectangle?

Back

A square has all four sides equal in length, while a rectangle has opposite sides equal in length.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0,0), move along the X-axis to the X-coordinate, and then move vertically to the Y-coordinate.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0,0) where the X-axis and Y-axis intersect, serving as the reference point for all other points.
