What is a unique property of a square's diagonals?

• A. They are unequal in length
• B. They intersect at right angles
• C. They do not bisect each other
• D. They are always equal in length

Answer: (D)

A unique property of a square's diagonals is that they are always equal in length. In a square, each diagonal connects opposite corners, forming two congruent triangles within the square. This congruence is a result of the square's symmetry and equal side lengths. Consequently, the diagonals not only are the same length, but they also bisect each other at a midpoint, creating two equal segments. This property helps reinforce the concept of symmetry and equality in geometric shapes, particularly for students learning about different quadrilaterals. Understanding this property is essential, as it forms the foundation for recognizing and working with squares and other geometric figures in mathematics.
