It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
A parallelogram, or selected irregular polygons with 5 or more sides
Pentagon
It can have none, one (1 pair), two (2 pairs), 3 (one triplet), 4 (two pairs), 5 (one pair + one triplet) or 6 (three pairs or two triplets) of parallel lines.
There are parallel lines, rectangles and arrays of stars 5 by 6 and 4 by 5.
Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
A hendecagon can have upto 5 pairs of parallel lines.
5 pairs of parallel lines, plus a set of 5 parallels.
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
A rectangular prism has three pairs of parallel lines. The top and bottom faces are parallel to each other, the front and back faces are parallel, and the two side faces are parallel. This makes a total of three pairs of parallel lines in a rectangular prism.
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.
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.
10, A decagon has a maximum of five pairs of perpendicular lines, and a maximum of 5 parallel lines. however, this isn't in black and white it can have no pairs of line either perpendicular or parallel. know write the answer clearly
12 faces. The number of parallel lines will depend on whether or not the prism is regular and right. In a regular right prism there are 10 parallel edges along the "length". 10 parallel lines make 45 pairs (1-2, 1-3, 1-4, ... 2-3, 2-4, ... etc). Each line at a base has one parallel line at the same base and two at the opposite base. Each such quartet makes 6 pairs of parallel lines and there are 5 such quartets - so 30 pairs of parallel lines in the bases. That makes a grand total of 75 pairs of parallel lines.
