cuboid
Any regular polygon with an even number of sides will have opposite angles of equal measure.
A polygon with 2n sides (n>1) can have opposite sides congruent.
No. Parallelograms have only 4 sides with 2 sets of parallel sides: they include squares, rectangles, and rhombuses (rhombi, diamond shapes). Because opposite angles are equal, each pair of parallel sides is equal in length. (For squares and "equilateral rhombi" all four sides are equal in length.)
this would be a rhombus. rhombuses are parallelograms (four-sided shapes with opposite sides parallel) that have all equal side lengths. squares are included as rhombuses.

Both shapes have 4 sides, two pairs equal in length. In a parallelogram the equal length sides are opposite each other. In a kite the equal length sides are adjacent.
It could be a parallelogram, but there are other shapes with more sides.
Any regular polygon with an even number of sides will have opposite angles of equal measure.
There are many such shapes. Any polygon with an even number of sides can have opposite sides that meet the above requirements.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
Both are quadrilaterals. A rectangle has 4 right angles, a rhombus has 2 pairs of equal angles (at opposite corners) A rhombus has 4 equal sides, a rectangle has 2 pairs of equal sides. The opposite sides in both shapes are parallel to each other.
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
There are a few simple shapes with equal sides. The basic shapes are a square, octagon, and an equilateral triangle,
A polygon with 2n sides (n>1) can have opposite sides congruent.
Most shapes do not have equal sides. In nature, shapes with equal sides are the exception rather than the rule.
