Heptagon diagonals.

For any interior angle that measures greater than 180°, there is also a corresponding diagonal that will lie outside of the boundaries of the heptagon. Because at least 1 angle of the heptagon must me greater than 180°, but not all can equal 180° (since the interior angles of a heptagon always sum to 900°), all concave heptagons are irregular.This gives the familiar result that the ratio of the diagonal to the edge of a regular pentagon is the golden mean t .
