Which shapes have no parallel sides?
The only polygon that absolutely positively never has any parallel sides is a triangle. Any other shape comprised of four or more straight line segments could have one or more pairs that are parallel.
Does a triangle have a set of parallel lines?
No. it is the only polygon that can not have parallel lines all though any regular polygon with an odd number of lines will have no parallel lines If three points were in a straight line it could be argued that these formed a triangle with parallel sides, though really it would be just a line; or if we had a triangle with infinite height the sides would be parallel. In any other case, no.
What is a four-sided polygon with opposite sides parallel?
A four-sided polygon with opposite sides parallel could be a square, a rectangle, or a rhombus.If it has one pair of opposite, parallel sides, then it is a trapezoid. If it has two pairs of opposite, parallel sides, then it is a parallelogram.
Why is a circle a polygon?
It takes an infinite number of sides to make a polygon into a circle, but you could still consider a circle to be a limiting state of the polygon, which all polygons approach as the number of sides increase.
What could be used as a rule to determine how many segments the Cantor Dust fractal has after the fourth iteration?
