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 : Diameter

The correct answer is: A. Rectangle : Diagonal

A diameter is a line that passes through the center of a circle and has endpoints on the circle. A diagonal is a line that connects two non-adjacent vertices of a

polygon. In a rectangle, all four sides are of equal length and all four angles are right angles. A diagonal of a rectangle is a line that connects two non-adjacent vertices.

The other options are incorrect because:

• A radius is a line that passes through the center of a circle and has one endpoint on the circle. It is half the length of a diameter.
• A square is a rectangle with four sides of equal length. It has four right angles.
• A bisector is a line that divides an angle into two equal parts.
