No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
always
Not all polygons are regular by definition. An irregular polygon may have non-congruent sides or non congruent angles or both. A regular polygon will always have both congruent sides and angles.
Yes. A square has two sets of equal and parallel opposite sides. All four sides and all four angles (right angles) are equal.
Since the sum of the exterior angles of a polygon is ALWAYS 360 degrees, (assuming this is a regular polygon), there will be 360 / 22.5 = 16 sides
A rhombus can be a square, but not necessarily.A square is always also a rhombus.A rhombus has 4 equal sides with opposite sides parallel and opposite angles equal.A square has 4 equal sides with opposite sides parallel and all angles 90o.
A Square is a polygon that is always regular.
Yes, a regular polygon is always equiangular.
a regular polygon is always equilateral
A square, pentagon, decagon, octagon are always regular polygons.
A regular polygon is always equiangular.
It can have parallel sides but not always.
No, a scalene triangle, for example, is a convex poygon but it is not regular.
Squares, rhombera, and equilateral triangles are always regular.
Not always
yes the radius of a regular polygon is always greater than the apothem
The angle bisectors of a regular polygon are always concurrent. And the point that they meet at is also the meeting point of the perpendicular bisectors of the sides. If it is a polygon with an odd nmber of sides, the "medians" [line from vertex to mid-point of opposite side] and "altitudes" [perpendicular from vertex to opposite side] will also meet at the same point.
The term regular polygon is almost always used to refer to a polygon that has equal interior angles and equal side lengths. In that light, the equiangular polygon and a regular polygon are the same thing.
