If it is 3D shape then it is not a polygon
All three are convex plane figures.
The triangle that has all three vertices touching the circle is called an 'inscribed triangle.' The circle has no special name, only the polygon inscribed.
No. A polygon is a flat structure like a triangle or circle. Diamonds are three-dimensional. It would most likely be classified as a polyhedron, as they are three-dimensional.

No. A three-sided polygon is, by definition, a triangle.
A triangle with three sides is a polygon.
because there is no other polygon that has three sides excpt a triangle!!!!!!!!!!!!!!!!!!!
a triangle is a polygon with three sides.
Isoceles triangular * * * * * Any triangle. Congruence is a relationship between two figures. Given any triangle you can always find another that it is congruent to.
Both are plane 2-dimensional figures. However, a triangle has three(3) straight sides. A circle does NOT have any straight sides, , but are constantly curving. Both are enclosed figures. The distance (radius) from a the centre of a circle to the circumference is constant. The distance from the 'centroid' of a triangle varies.
