A triangle need not have any parallel sides.
The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
Any polygon with four or more sides can have parallel sides.
Any polygon with 4 or more sides can have 2 parallel sides.
Any regular polygon with an even number of sides must have parallel sides.
You can construct any polygon with more than 4 sides such that two sides are parallel. A quadrilateral in which two lines are parallel is called a trapezoid.
Any regular polygon with 2k sides where k > 2. Also any such polygon that has been stretched in any directions parallel to its sides.
Any polygon with an even number of sides can have opposite sides that are congruent and parallel.
B. False
A decagon has 10 sides. Any regular polygon with four or more sides will have pairs of sides that are parallel. A decagon will have 5 pairs of parallel sides.
The number of pairs of parallel sides in a polygon varies depending on the type of polygon. For example, a rectangle has two pairs of parallel sides, while a trapezoid has one pair. Regular polygons, like a hexagon, typically do not have any pairs of parallel sides. Therefore, the total can range from zero to multiple pairs, depending on the specific polygon in question.
Any polygon with more than 3 sides can have two pairs of parallel sides.If it has only four sides and they make two parallel pairs, then it's a parallelogram.
Their are 4 pairs of parallel sides on an octagon. In fact, for any regular polygon with an even number of sides, there will be # of sides / 2 number of pairs of parallel lines.
