Regular Hexagon

Regular hexagon (a two-dimensional figure) is a polygon with six 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.
Long diagonal always crosses the center point of the hexagon.
Polygon (a two-dimensional figure) is a closed plane figure for which all edges are line segments and not necessarly congruent.
Short diagonal does not cross the center point of the hexagon.
Exterior angles are 60°.
Interior angles are 120°.
9 diagonals
6 edges
6 vertexs
