There are no specific names for such a shape.
Add the lengths of the four sides
Not necessarily. A quadrangle is a plane shape bounded by 4 straight sides. The name says nothing at all about the lengths of the sides.
Multiply half of the sum of the lengths of the top and bottom by half of the sum of the lengths of both sides
There is no specific name. The lengths of a quadrangle's sides do not uniquely identify its shape since the quadrangle can be flexed (skewed).
A quadrangle or quadrilateral (a shape with 4 angles or 4 sides, respectively). Special names normally come in when you DO have special characteristics, not when you don't.
A QUADRANGLE HAS 4 SIDES QUADRANGLE- QUAD MEANS 4
A quadrangle is a shape that has four right angles. It is also consider a parallelogram due to its four sides. Just think of a quadrangle as a square but different.
Just draw one! It can help if all the sides are different lengths. Draw three of the sides, making sure that the first and third sides are not parallel, then draw the fourth side, making sure it is not parallel with its opposite side.
The 3 sides have different lengths
Yes, a trapezoid is a quadrangle because a quadrangle has four sides and a trapezoid has four sides.
All three sides have different lengths.
How do you draw a quadrangle with no parellel sides?
