They are called heptagons.
Ah, what a happy little question! When you cut an octagon in half, you get two shapes called trapezoids. They have one pair of parallel sides and one pair of non-parallel sides, creating a unique and beautiful shape. Just like in painting, every shape has its own special charm and purpose.
A polygon with seven sides is called a septagon.
Five-sided shapes are called pentagons.

Shapes with 4 sides are called Quadrilaterals.There are special types of quadrilateral:Parallelogram, Rectangle, Rhombus, Square, Trapezoid, Kite.If it isn't one of those it is an irregularquadrilateral.
Any shapes that have seven sides.
They are called sides or edges.
A heptagon or a septagon. Equal-sided shapes are called "regular" so a seven equal sides shape is a regular heptagon.square square

Shapes with a specific number of sides are referred to as polygons. A shape with three sides is called a triangle, four sides a quadrilateral, five sides a pentagon, six sides a hexagon, seven sides a heptagon, eight sides an octagon, nine sides a nonagon, and ten sides a decagon. Each of these names is derived from Greek or Latin prefixes that denote the number of sides.
They are called hendecagons.
Any plane figure with seven sides is a heptagon.If all the sides are equal, and all the angles are equal, it is a regular heptagon.
