The name of a 150 sided polygon is Hectapentacontagon.
square because it has 4 sides
a nonagon is the name given to a nine sided polygon
there are 15 triangles in a 17 sided polygon
A 3-sided polygon has 0 parallel sides. A 4-sided polygon can have 0, 2 or 4 parallel sides. A 5-sided polygon can have 0, 2, 3 or 4 parallel sides. In general, an n-sided polygon can have 0, 2, 3, ..., n-1, or n parallel sides where n>5. A polygon with n sides can have n pairs of parallel sides (if n is even) or (n-1)/2 pairs if n is odd AND greater than 3. But it need not have any.

A color of a shape is not defined in a geometric definition. Therefore, be creative.
A parallelogram is a 4 sided polygon
All 4 sided quadrilaterals are polygons but a square is the only 4 sided regular polygon.
No because it is a 9 sided polygon whereas a parallelogram is a 4 sided polygon
A pentagon is a 5 sided polygon whereas a quadrilateral is a 4 sided polygon
Yes a rhombus is a 4 sided polygon
Yes a trapezoid is a 4 sided polygon.
