A quadrilateral or quadrangle.
An irregular polygon
Add together the lengths of all the sides that make up the boundary of the shape. These need not be straight lines.
It is a trapezoid that has one set of opposite parallel lines of different lengths.
Polygon: A closed shape bounded by straight lines.
retangle
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
If the shape has three straight lines and no other lines then it has to be a triangle
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.
A hexagon
Two straight lines connected by one curve is the basic horse-shoe shape.
A polygon is a shape that is a closed figure and has straight lines. example. A square
Not really, but if you have many lines it can look like a curved shape.
A trapezium (has only one pair of unequal parallel lines).
