Are polygons with all right angles sometimes squares?
Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.
What is the perimeter of a regular 15-gon with a radius of 3?
12
What are the flat shapes called?
They are polygons and they have 3 or more sides
What is a line segment that forms part of a polygon or a ray that forms one part of an angle?
It is called a "side" (in polygons, these may be called edges, but this can cause confusion with the term as used in 3-dimensional solids).
What are all the irregular polygons called?
Irregular polygons.
What is a shape with 3 side's called?
A shape with 3 sides is called a triangle. A triangle is a polygon and polygons have 3 or more sides.

A 12-sided polygon is called a dodecagon.

What is a 1 sided polygon called?
Polygons have 3 or more sides, so there are no one sided polygons idiot.
