A four sided figure with no parallel sides is a trapezium, but it is also an irregular four-sided polygon, tetragon, quadrilateral, or quadrangle.
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.
Any polygon with four or more sides can have perpendicular and parallel lines.
trapezoid
An irregular quadrilateral.
A square is a four-sided polygon with two congruent parallel sides.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
A four sided figure with no parallel sides is a trapezium, but it is also an irregular four-sided polygon, tetragon, quadrilateral, or quadrangle.
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
parallogram or quadrilateril
A four-sided polygon with all sides parallel and congruent is a rhombus. If all the angles are equal, it is a special case of a rhombus called a square.
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 trapezoid is a four sided polygon in which only two parallel side.
This is a trapezoid.
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 four or more sides can have perpendicular and parallel lines.
