A regular decagon;
A 20-gon with 2 lots of 10 congruent sides and angles in an alternating pattern;
A 30-gon with 3 lots of 10 congruent sides and angles in an 1-2-3-1-2-3 pattern; A 40-gon with 4 lots of 10 congruent sides and angles in an 1-2-3-4-1-2-3-4 pattern;
etc.
A regular polygon with an order of rotational symmetry of 5 is a regular pentagon. This means that the pentagon can be rotated by multiples of 72 degrees (360 degrees divided by 5) and still look the same. Each of its five sides and angles is equal, contributing to this symmetrical property.
360 ÷ 72 = 5, so that the regular polygon is a pentagon (a five-sided polygon).
Sum of exterior angles of any polygon is 360 degrees. So each being 72 degrees implies that there are 360/72 = 5 of them ie you have a regular pentagon.
If it's a regular polygon and each exterior angle measures 72 degrees then it is a pentagon which has 5 sides
360/72 ie 5 sides
360 ÷ 72 = 5, so that the regular polygon is a pentagon (a five-sided polygon).
Pentagon A+
The sum of all exterior angles of a polygon is 360 degrees. In a regular polygon, all of the exterior angle are equal, so there must be 360/72=5 sides of the polygon, which makes it a pentagon.
A pentagon has roatotional symmetry only if it is a regulat pentagaon. In that case, it has a rotational symmetry of 360/5 degrees and its multiples. That is, 72, 144, 216, and 288 degrees.
Sum of exterior angles of any polygon is 360 degrees. So each being 72 degrees implies that there are 360/72 = 5 of them ie you have a regular pentagon.
If it's a regular polygon and each exterior angle measures 72 degrees then it is a pentagon which has 5 sides
A regular pentagon.

If each interior angle is 175 degrees then the polygon will have 72 sides
5 sides and it is a regular pentagon
