A shape with four equal sides.

A shape with four equal sides.

• A. Square
• B. Rectangle
• C. Rhombus
• D. Kite

Answer: (A)

Four equal sides means every side of the shape is the same length. Among common quadrilaterals, a square is the shape that has four equal sides and also four right angles, which makes it the clearest example of "a shape with four equal sides" in this set. A rhombus also has four equal sides, but its angles aren’t necessarily right angles, so it’s not as specifically tied to the given description. A rectangle has opposite sides equal but not all four sides equal, and a kite has two pairs of equal adjacent sides. So the square is the best fit.
