Semi means half. So there are two semicircles in a circle.
The circle's diameter
When a circle is folded along its diameter, it creates two congruent halves or semicircles.
These are chords of a circle. If the chord passes through the centre of the circle it is the longest possible chord, divides the circle into two semicircles and is called a diameter.
It is TOBACCO.

It would divide the circle into two semicircles.

The diameter in the line through the circle that defines the 2 semicircles created.
I think they are similar because a triangle can fit into a circle and vise versa.

Because a bubble is part of a circle. It has an arc. An arc has no angles, it has degrees. semicircles are funny that way.
It is TOBACCO.

There are infinitely many. Amongst them are: Circle, ellipse, annulus (disk), Triangle, quadrilateral, pentagon, hexagon, and polygons with more sides, Semicircles, quadrants, octants, and other combinations of the above, Irregular 2d shapes - like a blob.
