It is a regular 9-sided nonagon.
48 sides A formula for finding the number of sides of a regular polygon given an interior angle: 360/(180-angle)=sides
A regular polygon has all sides equal and all angles equal.
There is no name given to it. (As the number of sides increases, the upper limit of a regular polygon is a circle.)
a "regular" one
That regular polygon would have 9 sides.
A polygon with eight sides, regular or not, is an octagon. There isn't a special name for a regular octagon (other than "regular octagon").
All the sides are the same length
By dividing the given exterior angle into 360 degrees tells you how many sides the polygon has.
48 sides A formula for finding the number of sides of a regular polygon given an interior angle: 360/(180-angle)=sides
A regular polygon has all sides equal and all angles equal.
Among all polygons with a given perimeter, the regular polygon that maximizes the area is the circle, although a circle is not technically a polygon. If we restrict our consideration to polygons, a regular polygon with more sides (such as a regular hexagon or dodecagon) will generally have a larger area than one with fewer sides, given the same perimeter. Thus, for polygons specifically, a regular polygon with a high number of sides will have the largest area.
A regular polygon is a polygon with congruent sides and interior angles.
There is no special name for that. However, if the sides are also equal, it is called a regular 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 that has congruent sides and congruent angles is called a Regular polygon. If the number of sides is given, you can be more specific. Some examples: 3 congruent sides/angles = equilateral triangle 4 congruent sides/angles = square 5 congruent sides/angles = regular pentagon 6 congruent sides/angles = regular hexagon ...and so on, by adding "regular" in front of the shape's name.
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.
There is no name given to it. (As the number of sides increases, the upper limit of a regular polygon is a circle.)
