Front

What is the length of the line segment PQ if it measures 9 units?

Back

The length of the line segment PQ is 9 units.

Front

Which coordinates could be the fourth point to form a rectangle?

Back

The coordinates (3, -6) could be the fourth point to form a rectangle.

Front

What is the length of the longest side of a rectangle with coordinates (3, 2), (-2, 2), (-2, -1), (3, -1)?

Back

The length of the longest side of the rectangle is 5 units.

Front

Define a rectangle.

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and four right angles.

Front

What are the properties of a rectangle?

Back

1. Opposite sides are equal in length. 2. All angles are right angles (90 degrees). 3. Diagonals bisect each other and are equal in length.

Front

How do you calculate the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

The length of the line segment is calculated using the formula: √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance between the points (3, 2) and (3, -1)?

Back

The distance is 3 units.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated as: Area = length × width.

Front

If a rectangle has a length of 7 units and a width of 3 units, what is its area?

Back

The area of the rectangle is 21 square units.

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated as: Perimeter = 2 × (length + width).
