Right triangles have a set of perpendicular lines and no parallel lines.
all right some body said that Ellipse Circle Oval but parallel shapes need to have lines so they are not parallel shapes so all i know that are not parallel is a diamond and a rhombus
parrelel lines meet
2
circle
An infinite number of shapes.
A trapezoid, trapezium and a pentagon have only 1 set of parallel lines.
trapezoid
Rectangles and squares
Put 2 lines on the perpendicular sides and put 1 line for the parallel sides
Any polygon with four or more sides can have parallel lines. So also can some irregular shapes.
Four parallel lines would not correspond to any of the commonly taught shapes. Two pairs of parallel lines would be characteristic of the square, rhombus, rectangle, and parallelogram
