The sum of the internal angles of a 7-sided polygon equals 900 degrees.
It is 180x5=900 degrees
A seven sided figure is called a heptagon.
if you mean diagonals i don't know maybe 9
None!!!! A 7-sided polygon is named 'HEPTAGON'., However, An 8-sided polygon is named 'OCTAGON'.

heptagon * * * * * No. That is a 7 sided figure. A 17 sided figure is a heptadecagon.

A seven sided figure is called a heptagon.
7x180-360 or (7-2)x180 900 degrees
The interior angles of a heptagon add up to 900 degrees
Septagon
Exterior angles add up to 360 degrees and interior angles add up to 900 degrees in a 7 sided heptagon
The interior angles of a 7 sided polygon add up to 900 degrees
a sectagon
