Polygons are 2D plane figures. All polygons with 7 sides would be classified as heptagons.
Regular polygons with 5, 7 or more sides.
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
Infinitely many. Polygons with 6 or more sides can have 3 pairs of parallel lines. Polygons with 7 or more sides can have a set of three parallel lines.
Hexagons are 2-D polygons with six sides.
You cannot tessellate convex polygons with 7 or more sides.
A parallelogram and selected polygons with 6 or more sides.
Quadrilaterals. Parallelograms have two pairs of parallel sides.
Any polygon with 4 or more sides can have 2 parallel sides.
trapezoid
because polygons are closed shapes with no rounded parts so a 2 sided polygon is not real!
hi polygons are named according to their no of sides for example a polygon having 5 sides is named as pentagon polygon having 6 sides is known as hexagon 7 sides has named as heptagon and so on
