The following question, consist of two words each that have a certain relationship to each other, followed by four lettered pairs of words. Select the lettered pair that has the same relationship as the original pair of words: Circle : Circumference :: Square : ?

The answer is D. Perimeter.

A circle is a two-dimensional shape with all points equidistant from a center point. The circumference of a circle is the distance around the circle. The perimeter of a square is the distance around the square. Both the circumference of a circle and the perimeter of a square are measured in linear units, such as inches, feet, or meters.

• Volume is the amount of space enclosed by a three-dimensional shape. A square is a two-dimensional shape, so it does not have a volume.
• Area is the amount of space enclosed by a two-dimensional shape. A square is a two-dimensional shape, so its area is measured in square units, such as square inches, square feet,

  or square meters.
• Diagonal is a line segment that connects two non-adjacent vertices of a polygon. A square has four vertices, so it has four diagonals. The length of a diagonal of a square is not related to the perimeter of the square.
