a square
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
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.
right triangle
triangle
No it can't, because if a triangle has two parallel lines then it ceases to be a triangle and becomes quadrilateral or a polygon.
A hexagon and a triangle
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.
Yes. A triangle is a type of polygon and it has NO parallel sides!!!!!!!
Not all polygon have two pairs of parallel sides. For example, a square will, but not a triangle.
A triangle need not have any parallel sides.
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
A four-sided polygon with opposite sides parallel and all sides congruent is a square.
