A rectangle has four equal angles (each measuring 90 degrees) and two pairs of matching sides, with opposite sides being equal in length. Additionally, a rectangle has two lines of symmetry: one vertical and one horizontal.
An irregular pentagon such as a child's silhouette of a house: a rectangle shape (open at the top) forming the body of the house, with a triangular roof on of the rectangle. The vertical line through the apex of the roof is the line of symmetry. The two walls, and the two roof lines are the two sets of equal sides. The two right angles at the base are the one set of matching angles.

A rhombus and a hexagon are both polygons, meaning they are closed shapes with straight sides. They also both have equal interior angles - a rhombus has four equal angles, while a regular hexagon has six equal angles. Additionally, both shapes have lines of symmetry - a rhombus has two lines of symmetry, and a regular hexagon has six lines of symmetry.
