Distance and Perimeter on the Coordinate Plane

Front

What is the distance formula used to find the distance between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width)

Front

What is the length of a vertical line segment between two points with the same x-coordinate?

Back

The length is the absolute difference of their y-coordinates.

Front

What is the length of a horizontal line segment between two points with the same y-coordinate?

Back

The length is the absolute difference of their x-coordinates.

Front

If point A is at (2, 3) and point B is at (2, -1), what is the distance between them?

Back

Distance = 4 units

Front

If point C is at (5, 5) and point D is at (5, 10), what is the distance between them?

Back

Distance = 5 units

Front

What is the perimeter of a rectangle with corners at (0, 0), (0, 4), (3, 4), and (3, 0)?

Back

Perimeter = 14 units

Front

How do you find the distance between two points on a vertical line?

Back

Use the absolute difference of their y-coordinates.

Front

How do you find the distance between two points on a horizontal line?

Back

Use the absolute difference of their x-coordinates.

Front

What is the perimeter of a rectangle with a length of 8 units and a width of 3 units?

Back

Perimeter = 22 units
