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.
Assuming you cut it at the angles, the answer is " A Polygon" of 5 sides, also called an irregular pentagon. If you were to cut the octagon along the straight lines, the answer would still be a polygon but then it would have 6 sides and be called an irregular hexagon. For example, cutting a stop sign vertically down the middle would give you a six sided polygon.
It is called a frustrum
hemisphere
An eight sided shape is called an octagon.
An octagon. Or more specifically, an irregular octagon.

get a cut out shape of octagon, then get cut out triangles and try to fit in the triangles covering all the octagon but here is the solution... j
As an octagon has 8 angles, a square has 4 as has a rectangle
YES
It is called a frustrum
To cut something in half is called "halving." This involves dividing an object or quantity into two equal parts.
To turn a 9x9 square into an octagon you can cut corners off the square. It will not be a regular octagon though.
hemisphere
Simply that: "irregular octagon".
Whats a diagram
It becomes an hemisphere
It is called symmetry. When an object is cut in half and both sides are identical, it exhibits symmetry.
