Regular polygon is equilateral and equiangular.
Irregular polygon is non-equilateral and non-equiangular.
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.
A non regular or irregular polygon is a polygon whose sides are not all the same length
An isosceles triangle or a rhombus.
In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.
Any polyhedrons such as a cube is a non polygon
All the sides of a regular polygon have the same length. If two or more sides of a polygon have different lengths, then the polygon is not regular.
A polygon is 2 dimensional shape whereas a non polygon can be 3 dimensional shape
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.
A non regular or irregular polygon is a polygon whose sides are not all the same length
A regular polygon is a polygon whose sides are equal length and whose angles are all the same value. A non regular polygon is just the opposite of a regular polygon.
The ogive never close because they represent non-decreasing functions, and polygon you close it.
a polygon in which the sides are not all the same length
A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.
A circle is non-polygon. Meaning it has a curved side. A circle has no sides. It is non-regular.
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.
All the sides are not equal
An isosceles triangle or a rhombus.
