Answer:
Heptagon!
Step-by-step explanation:
A polygon is broken up into 5 non-overlapping triangles.
Hence, the interior angle sum is = 5\180=900 degrees
The sum of the interior angles of a convex polygon is given by:
(n-2)180 degrees.
(n-2)180=900
180n-360=900
180n=1260
n=7
A seven sided figure is a Heptagon
Therefore the answer is Heptagon!
Octagon
