The triangle is a rigid shape, more so than a square, for example.
Some do, some don't. And the reason is that the area depends on the dimensions as well as the shape.
No. A triangle is the only rigid polygon.

A triangle has 3 sides, a square has 4 sides, an hexagon has 6 sides and a polygon has 3 or more sides.

No more unusual than the right isosceles triangle, which is a diagonally-bisected square.
a quadrilateral such as a square, rhombus, or rectangle
It is a three sided polygon and has all the characteristics of a polygon. The only additional property that it has is that it is a rigid shape. All polygons with four or more sides can be distorted: a square into a rhombus, for example. But the sides of a triangle uniquely determine its angles.
No it is not: any shape with four or more sides which are connected pair-wise is not rigid.

Triangle Square Pentagon Hexagon Octogon Rumbus etc lol
No, diamond is not a triangle shape. Diamond is a four-sided figure with two pairs of parallel sides that are not equal in length. It is more commonly described as a rhombus shape, which is a type of quadrilateral.
