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?

A 7sided figure is called a heptagon.
A 7 sided figure cannot look like an octagon, an octagon has 8 sides! 
If it is a solid, not plane figure, it is a Heptahedron.
