Pentadecagon, Quindecagon, PentakaidecagonA polygon with fifteen sides can be called a pentadecagon.
In geometry, a pentadecagon (or pentakaidecagon) is any 15-sided, 15-angled, polygon. A regular pentadecagon has interior angles of 156°, and with a side length a, has an area given by: A= 15/4 * a²* cot π/15 = (15a²)/8 (√3 + √15+ √2* √(5+√5)) ≈ 17.6424 a²
A pentadecagon, quindecagon or pentakaidecagon
A Pentadecagon had 15 sides
The name of a 15 sided polygon is Pentadecagon.
it is called a pentadecagon ok? its like pentagon but its a pentadecagon.
A pentadecagon has 15 sides. (the prefixes pent=5, and deca=10)15
its a pentadecagon i.e, a polygon with 15 sides. in a regular pentadecagon each angle is of 156 degrees
Perimeter = Length of side 1 + Length of side 2 + Length of side 3 + Length of side 4 + Length of side 5 + Length of side 6 + Length of side 7 + Length of side 8.
IT has 15 sides
