Two quadrilaterals that have two pairs of equal sides are:
-
Rectangle: A rectangle has pairs of equal sides, with opposite sides being equal in length. Additionally, all interior angles are right angles.
-
Rhombus: A rhombus also has pairs of equal sides, with all four sides being of equal length. The opposite angles are equal, and the diagonals bisect each other at right angles.
Both shapes are examples of quadrilaterals with specific properties of equal side lengths.
