A trapezoid has at least one set of parallel lines, but they need not be the same length. Here is a picture of one with parallel sides, but clearly not the same length Dr. Chuck (picture is from http://illuminations.nctm.org/LessonDetail.aspx?ID=L580)

A wire of length 3x is bent into the shape of a square Express the area A of the square as a function of x?
The square is formed from a wire the length of 3x, which forms a perimeter of the same length. Because each side of the square is one fourth of the total perimeter (1 out of 4 equal sides), each side is 3x/4. The square of one side of a square is equal to the area of that square, so the area is (3x/4)2 = (9/16)x2.The answer is then A = (9/16)x2.
Two lines that lie in the same plane and are always the same distance apart?
parallel lines
Are skew lines parallel?
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
Is 6 symmetrical?
no ****************** Draw a vertical line through the centre of the number 6. As both sides are not identical, then there is no symmetry. Do the same with a capital H, and there is symmetry, as both sides of the vertical line are identical.
What is produced when you slice a cone at different angles?
When a cone is sliced parallel to the base then the shape produced is a circle. If the cone is sliced at an angle so that the cut goes completely through the cone then an ellipse is produced. If the cut is made perpendicular to the cone's base then the shape produced is a parabola.
Does each side of a shape have to be the same length to be parallel?
No. The sides of a shape don't need to be equal in length to be parallel.
What shape are you you have four sides no parallel sides 2 of your sides are the same length and the other 2 are the same length?
A kite
What shape has opposites sides parallel and the same length and four right angles?
A shape with opposite sides parallel and of the same length and four right angles is a rectangle.
What shape has opposite sides that are parallel and the same length?
A Paralellogram
What shape has 4 sides 1 pair of parallel sides and no sides are the same length?
A trapezoid
Which shape has 2 parallel sides and all the sides are the same length?
A square or a rhombus
What shape has pairs of sides next to each other and have the same length and there are no parallel sides?
triunghiul echilateral
What is a square shape?
A four sided figure with all sides the same length and opposite sides parallel.
A shape with no right angle with a reflex angle four sides two parallel sides and have the same lenght?
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
What shape has 4 sides has 2 pairs of parallel sides all the sides are the same length has no right angles?
A Rhombus
A four sided shape that has two pairs of sides the same length but no parallel lines?
A kite
What is a shape with 4 sides of the same length parallel to each other called?
A square or a rhombus
