All triangles are polygons, having three straight-line sides. However, a right triangle is not a "regular polygon" because the three side lengths and interior angles cannot be the same (the right angle takes up 90 degrees of the total 180). An equilateral triangle is a regular polygon.
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
Circles, some triangles, and irregular polygons
Yes triangles are 3 sided polygons
No. Only triangles and cyclic polygons can be circumscribed.

All triangles are polygons, so you just call them triangles.
Scalene triangles, rectangles, rhombi, concave polygons with 5 or more sides.

The reguar polygons are triangles, quadrilaterals and hexagons.
