Any regular polygon with an even number of sides will have opposite angles of equal measure.
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.)
The only similarities between these shapes are that:These shapes have all congruent interior anglesObviously, the shapes are regular and have equal sides.
A Square
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.
Squares have four sides of equal length. In rectangles, the opposite sides are equal to one another. In both shapes, the internal angles are all 90°.
Yes. If a pair of opposite sides are not equal, then you don't have a parallelogram.
-- Opposite sides are parallel.-- Opposite sides are equal.-- Angles are all equal.
equilateral is all equal sides so the opposite would be scalene: no equal sides
Opposite
No, both shapes have all four sides equal.
A rhombus has all sides equal and opposite sides parallel. This includes a square which is a special case of a rhombus with all angles equal (90 degrees) as well. If opposirte sides are equal but not all sides are equal, it is a parallelogram
