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.
A four-sided polygon with two parallel sides is called a trapezoid. In a trapezoid, the two parallel sides are known as the bases, while the non-parallel sides are called the legs. The parallel sides of a trapezoid are of different lengths, distinguishing it from a parallelogram where both pairs of opposite sides are parallel and equal in length. The sum of the interior angles of a trapezoid is always equal to 360 degrees.
in geometry i learned a parallelogram has only 2 pairs of parallel sides each pair of opposite sides is parallel
Yes. A square has two sets of equal and parallel opposite sides. All four sides and all four angles (right angles) are equal.
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
-- A trapezoid always has.-- Any polygon with more than four sides can have, but doesn't always.
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.
