Geometric and angular shapes are general classes of shapes associated with geometry and with geometry/trigonometry respectively. The two terms ("geometric shapes" and "angular shapes") are very general in nature, and it isn't really "doable" to make a list of all the geometric and angular shapes one may encounter.
The general shape is "bent".
That will depend on what they are but in general 3D shapes have surface area and volume whereas 2D shapes have only surface area.
it means i think shapes and lines
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
I'm pretty sure its a polygon
They are plane (2 dimensional or flat) figures. They are closed shapes. They are bounded by four straight sides. Then there are others that follow from the general attributes of polygons.
If you are talking about the shapes of the planets themselves, then that would be a sphere. However, if you are talking about the shapes of their orbits, that would be an ellipse, which is a fancy term for an oval.
Actually the trapezium is a shape. Trapezoid is the general group term for shapes of it's general shape. It has only two parallel sides.
There are many 3-D shapes (including ones that don't have names). Here are the commonly known 3-D shapes in general: -hemisphere -cube -cuboid -tetrahedron -cylinder -octahedron -cone -prism -sphere -pyramid -dodecahedron
Perimeter = The sum of the lengths of each side. There may be special rules applicable to selected shapes, but the above is the only general rule - in answer to the general question.
Polygon * * * * * A polygon, although correct, is too general a term. "Triangles" is better.
