To have no symmetry the four sides would all have different lengths, and each angle would also be different. The figure would not look like a square or a rectangle, but would instead be an irregular 4-sided polygon.

Any 4 sided shape is a quadrilateral. If all sides are of different lengths, that is as specific as you can get. Other 4 sided shapes have special characteristics about them, so they are given special names. They are still quadrailaterals.

That would be "perimeter". The perimeter is the distance around a figure, and it is calculated by adding the lengths of the different sides. For example, for a triangle, add the lengths of the three sides.

No because a trapezoid has only one pair of parallel sides of different lengths whereas a parallelogram has two pairs of parallel sides of equal lengths but they are both four sided quadrilaterals.

It depends on what you are summing together: the lengths of the sides - to find the perimeter - or the exterior or interior angles - to satisfy a maths question.

Yes, a quadrilateral is a four sided figure and a parallelogram has on top of this property the requirment that the opposite sides are parallel and equal in lengths.

An isosceles trapezoid is a 4 sided quadrilateral having one pair of opposite parallel sides of different lengths and its two slanted sides are of the same lengths and it has one line of symmetry.

A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.

A regular polygon is a figure with a definite shape and closed on all sides. An equilateral triangle is a three sided regular polygon whose sides have equal lengths.

A trapezoid is a 4 sided quadrilateral which has one pair of parallel sides of different lengths. Its perimeter is the sum of its 4 sides. Its area is: 0.5*(sum of parallel sides)*height

a 4 sided figure where there are 2 sets of parallel sides, and all angles are 90 degrees. A rectangle is a quadrilateral with four right angles. Pairs of lengths can be equal, as in a square; or they can be different, like a sheet of paper. like a square but two sides are longer than the other two

A trapezoid is a 4 sided quadrilateral with 1 pair of opposite parallel sides of different lengths. Its perimeter is the sum of its 4 sides. Its area is: 0.5*(sum of parallel sides)*height

They are both 4 sided quadrilaterals with a parallelogram having 2 pairs of parallel sides whereas a trapezium has only 1 pair of parallel sides of different lengths

They are all 4 sided quadrilaterals but a trapezoid is different from the rest of them because it has only 1 pair of parallel sides of different lengths whereas all the rest have 2 pairs of parallel sides. A kite is also a 4 sided quadrilateral

Any four sided figure will actually fit this description, regardless of shapes or side lengths. The sum of the angles of every four sided figure, no matter what the dimensions of each individual side may be, is always 360 degrees.

A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.

You are a scalene triangle. If you were to have two of the same sides similar, you would be an isoceles triangle. If you were to have all of your sides the same, you would be an equilateral triangle.

A 4 sided trapezoid can also be transformed into a 4 sided isosceles trapezoid which will have equal base angles and 1 line of symmetry. Both have a pair of opposite parallel sides of different lengths.
