Polygons are plane closed figures bounded by straight lines. There cannot be polygons with fewer than 3 sides.
That one.
equilateral triangles and regular pentagons
There are an infinite number of different polygons, and some have them have more than one name.
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.

Yes they are polygons as they have more than 1 side.
A pentagon, a heptagon and an endecagon.
polygon of more than 4 sides and a triangle.
3D means that they have three dimensions, which are height, width and depth. 3D figures are solid shapes such as cubes and spheres, rather than their 2D equivalents which would be squares and circles.
There are several types of polygons, including regular polygons, which have equal sides and angles, such as a square or equilateral triangle. There are also irregular polygons, which have different side lengths and angles, such as a rectangle or pentagon. Finally, there are convex polygons, where all interior angles are less than 180 degrees, and concave polygons, where at least one interior angle is greater than 180 degrees.
