Polygons on the Coordinate Plane

Front

What is a polygon?

Back

A polygon is a closed figure made up of straight line segments. Examples include triangles, rectangles, and squares.

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is the perimeter of a polygon?

Back

The perimeter is the total distance around the polygon, calculated by adding the lengths of all its sides.

Front

How do you find the area of a square?

Back

The area of a square is found by squaring the length of one of its sides (Area = side × side).

Front

What is the distance formula on a coordinate plane?

Back

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

Front

What are the coordinates of a point?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on a coordinate plane.

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated by adding the lengths of all four sides or using the formula: Perimeter = 2 × (length + width).

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).

Front

What is the formula for the area of a square?

Back

The area of a square is calculated using the formula: Area = side².
