Right triangles have a set of perpendicular lines and no parallel lines.
A trapezoid has one set of parallel lines.
A parallelogram always has one set of parallel lines, plus another set also.A trapezoid (trapezium) always has exactly one set of parallel lines and no more.Any shape with more than four sides can have one set of parallel lines, but doesn'tnecessarily have to.
A rectangle actually has two sets of parallel lines. Each pair of opposite sides is parallel to each other, meaning there are two sets: one set of parallel lines for the length and another set for the width. Thus, a rectangle does not just have one set of parallel lines; it has two.
parallel lines = a set of parallel lines above
trapezoid
A trapezoid, trapezium and a pentagon have only 1 set of parallel lines.
Yes. The top and bottom lines of a trapezoid are parallel.
A circle does not have a set of parallel lines in the traditional sense, as parallel lines are defined as lines that never intersect and remain equidistant from each other. However, you can draw lines that are tangent to a circle at various points, and these tangent lines can be parallel if they are at the same distance from the center of the circle. But in the context of the circle itself, it does not contain parallel lines.
It is a trapezoid that has one set of opposite parallel lines of different lengths.
Parallel lines are line that don't intersect like the equal sign = .
There isn't a name...they're just called a pair of parallel lines.
