I knew that heptagons that have six obtuse angles.Ha Ha! Super Shapes! That was not wrong!
Heptagons have seven sides.

A heptagon has seven sides, and an octagon has eight sides. 4 heptagons and 5 octagons then have (4*7)+(5*8) = 68 sides altogether

900 degrees
We need an answer! We need an answer! Heptagons only have seven angles.Great! Super Shapes! That's correct!

The 7 interior angles of a heptagon add up to 900 degrees
The seven sides, in order, must be congruent, as must the seven angles.
Heptagons have seven sides.
Because - the angles formed where each face joined, would prevent you forming a polyhedron.
The inside angles total 180 degrees, and the outside angles total 360 degrees. It is the same for triangles, parallelograms, rectangles, squares, trapezoids, hexagons, heptagons, octagons, and all enclosed plane figures.

Not many: it's an awkward shape to make because its angles are 7/360 degrees. Two examples are the 50 pence and 20 pence coins in UK currency, but they are only based on heptagons, not actual heptagons because their sides curve. The 50p coin (physically the larger of the 2) is a shape of its own that can be rolled fairly smoothly.
