I have a 7 sided shape that looks like an octagon, but it only has 7 sides. Is it a rhombus, a square, a parallelogram, a kite, a rectangle, a trapezoid, a chevron, or just a quadrilateral?

Answer 1

A 7-sided figure is called a heptagon.

A 7 sided figure cannot look like an octagon, an octagon has 8 sides!

Answer 2

If it is a solid, not plane figure, it is a Heptahedron.
