Coordinate Plane - Polygon

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair (x, y).

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 identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) and represents the horizontal position on the coordinate plane.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) and represents the vertical position on the coordinate plane.

Front

What is the formula for the perimeter of a square?

Back

The perimeter of a square is calculated using the formula P = 4s, where s is the length of one side.

Front

If a square has a perimeter of 20 units, what is the length of each side?

Back

Each side length is 5 units, calculated as 20 units ÷ 4.

Front

What is the distance between two points on a horizontal line?

Back

The distance between two points on a horizontal line is the absolute difference of their x-coordinates.

Front

What is the distance between two points on a vertical line?

Back

The distance between two points on a vertical line is the absolute difference of their y-coordinates.

Front

How do you find the missing coordinate of a rectangle?

Back

To find the missing coordinate of a rectangle, use the known coordinates and the properties of rectangles (opposite sides are equal and parallel).

Front

What does the point (0, 0) represent on a coordinate plane?

Back

The point (0, 0) is called the origin and represents the intersection of the x-axis and y-axis.
