Polygon Angles Calculator
Calculate polygon angles with explicit inputs and a worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Simple planar polygon. Individual angles shown assume a regular convex polygon.
Example Calculation
- Number of sides: 6
A hexagon has interior angle sum 720°; if regular, each angle is 120°.
Frequently asked questions
How do I use this calculator?
Enter number of sides. The result updates automatically. Use Reset to restore the example values.
What method does it use?
interior sum = (n−2)180°; regular interior = (n−2)180°/n. Simple planar polygon. Individual angles shown assume a regular convex polygon.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
