A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
Trapizium
A trapezoid/trapezium is a quadrilateral (4 sided shape) with exactly one pair of parallel sides.It is a quadrilateral (a closed plane shape with four linear sides) that has at least one pair of parallel lines for sides
A regular hexagon.
a house shape: a floor, 2 parallel walls and an angled roof
The figure that has 4 pairs of parallel lines and 8 obtuse angles is a rectangular shape known as a rhombus. A rhombus is a quadrilateral with all sides of equal length and opposite angles of equal measure. In a rhombus, each pair of opposite sides are parallel to each other, resulting in 4 pairs of parallel lines. Additionally, since a rhombus has 4 angles greater than 90 degrees, it will have a total of 8 obtuse angles.
A square
Strictly speaking, the answer is no. There is an implicit assumption that parallel lines refer to straight lines and, since there are no straight lines in a rainbow, there cannot be any parallel lines. The lines are concentric and so they never meet.
A trapezoid.
a regular square!
It is a plane shape bounded by four straight lines, a pair of which are parallel.
A trapezoid has two parallel lines.
A rhombus has parallel lines but no perpendicular lines.
Trapezoid in American English and Trapezium in British English.
Any shape that contains a section of a plane can have an infinite number of parallel lines in it.
There is no shape that has sides that are all parallel to each other. That would just be a collection of straight lines.
Polygon: A closed shape bounded by straight lines.
It is a trapezoid. If the 2 nonparallel sides are congruent, then it is an isosceles trapezoid.
