It has 9 sides and it can be an regular or a irregular polygon which is called a nonagon Check: 0.5*(81-27) = 27 diagonals
a "regular" one
That regular polygon would have 9 sides.
It is an equilateral polygon. It is not a regular polygon. For the polygon to be regular, it is not enough for the sides to be congruent: all the angles need to be congruent as well.
A polygon whose sides are all equal is known as a regular polygon. Some examples include squares and equilateral triangles.
It has 9 sides and it can be an regular or a irregular polygon which is called a nonagon Check: 0.5*(81-27) = 27 diagonals
A regular polygon is a polygon with congruent sides and interior angles.
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 regular polygon is a polygon in which all sides and angles are congruent, so a rectangle is a regular polygon when it is a square: when all sides are equal.
A polygon with 27 sides would be called an icosakaiheptagon.
A regular polygon has equal angles AND sides.
no a regular polygon has 360 degrees and it can have 4 or more sides
a "regular" one
5 sides, a regular pentagon.
for it to be a regular polygon it has to have 3 sides or less
That regular polygon would have 9 sides.
360/exterior angle = number of sides of a regular polygon
