A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.

A trapezoid or, in Britain, a trapezium. Other than in Britain, a trapezium is a quadrilateral with no parallel sides at all.

A square, a rectangle, a parallelogram.
There is no such polygon.
A regular polygon is a polygon in which all the angles and sides are equal, say on a regular polygon if one side is 15cm if you know that they are all equal, all the other sides are 15cm, also you can assume on a regular polygon, that if one angle is 75o all the other angles are 75o
they came from how many sides are on the polygon
a polygon
It is a regular polygon
If every side of the polygon is the same length, then it is a regular polygon. If the measure of every internal angle of a polygon is the same as every other, then it is a regular polygon. The two always go together, so you need to check only one of the above criteria.
A square or any other regular polygon
Inscribed Polygon
A polygon with eight sides, regular or not, is an octagon. There isn't a special name for a regular octagon (other than "regular octagon").
Most regular polygons will not - by themselves. In fact, of the regular polygons, only a triangle, square and hexagon will. No other regular polygon will create a regular tessellation.
Equilateral triangle or any other type of a regular polygon.
