A quadrilateral
NO!!!! A parallelogram is a polygon of four sides. The opposite sides are parallel and equal in length.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
The four sides are NOT parallel. If the fours sides were parallel , it would NOT be a polygon., but just four lines. The opposite sides are parallel. Being the same length, it could be either a 'SQUARE' or a 'RHOMBUS'. The difference being that the square has four right angles (90 degrees)-. A Rhombus has the opposite angles the same, but not a 90 degrees.
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.
In parallelogram each two opposite sides are parallel and equal in length
A square.
NO!!!! A parallelogram is a polygon of four sides. The opposite sides are parallel and equal in length.
A regular polygon with an even number of sides.
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
The four sides are NOT parallel. If the fours sides were parallel , it would NOT be a polygon., but just four lines. The opposite sides are parallel. Being the same length, it could be either a 'SQUARE' or a 'RHOMBUS'. The difference being that the square has four right angles (90 degrees)-. A Rhombus has the opposite angles the same, but not a 90 degrees.
Any polygon with an even number of sides can have opposite sides that are congruent and parallel.
a trapezoid
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.
Any even sided irregular polygon can have opposite sides parallel. A parallelogram would be the simplest of these.
