Regular Heptagon
Regular heptagon (a two-dimensional figure) is a polygon with seven congruent sides.- Circumcircle is a circle that passes through all the vertices of a two-dimensional figure.
- Congruent is all sides having the same lengths and angles measure the same.
- Diagonal is a line from one vertices to another that is non adjacent.
- Inscribed circle is the largest circle possible that can fit on the inside of a two-dimensional figure.
- Polygon (a two-dimensional figure) is a closed plane figure for which all edges are line segments and not necessarly congruent.
- Exterior angles are 51.429°
- Interior angles are 128.571°
- 14 diagonals
- 7 edges
- 7 vertexs
Area of a Regular Heptagon formula
| \(\large{ A_{area} = \frac {7} {4} \;a^2 \; \cot \;\left( \frac {180°} {7} \right) }\) |
Where:
\(\large{ A_{area} }\) = area
\(\large{ a }\) = edge
\(\large{ \cot }\) = cotangent
Edge of a Regular Heptagon formula
| \(\large{ a = \frac {p}{7} }\) |
Where:
\(\large{ a }\) = edge
\(\large{ p }\) = perimeter
