The name tells you how many sides. If you are given one external angle, say A, then you know that the number of sides multiplied by A =360 since the sum of the exterior anlges is 360. If you are given the sum of the interior angles, you can find the number of side using the formula that sum of interior angles =(number of sides-2)180 degrees.
If it is a regular polygon then it will have 10 sides
A regular polygon that has 180 degrees is an equilateral triangle.
It has 360/20 = 18 sides
12 sides
Providing that it is a regular polygon it will have 5 sides
no a regular polygon has 360 degrees and it can have 4 or more sides
That regular polygon would have 9 sides.
5 sides, a regular pentagon.
If it is a regular polygon then it will have 10 sides
No regular polygon has 160. The "smallest" polygon is the triangle, which has 180o. ^^FALSE!!!!!!! this polygon has 18 sides!
5 sides and it is a regular pentagon
A regular polygon that has 180 degrees is an equilateral triangle.
The polygon has 16 sides :)
15 sides
The polygon would have 72 sides...
15
It has 14 sides! The regular polygon with 14 sides is called a tetradecagon.
