A dodecagon has 12 sides
Twelve.
the lines on it NOT the corners!
Press the buttons in the edge and move the shapes into the same shapes.
Hendecagon is 11. Dodecagon is 12.
Hard-Edge
The answer could depend on the way in which the shapes are connected but I doubt that it has any specific name.
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.
well a honey container is twelve ounces also a hot sauce container is twelve ounces
A place where two faces meet is called an edge.
A pentomino is a geometric shape formed by connecting five squares edge to edge. There are 12 distinct pentominoes, which can be classified into various shapes such as straight, L-shaped, and more complex configurations. These shapes can be rotated and reflected, but the 12 unique forms remain constant.
Circle. Ellipse. Rectangle. Square. Triangle. Parallelogram. Trapezoid. Losenge. Deltoid. Pentagon. Hexagon. Parabola. That's twelve.
An edge is the curve formed where two of the planes defining [bordering] the 3D shape meet. It is often a straight line where the planes defining the shape meet but, as in the case of a hemisphere, an edge could be a circular boundary where the flat face meets the curved face.
