Depending on their shapes and sizes you can make plane shapes with 3 to 24 sides.
this question made me laugh so i shall answer it Well since triangles are the strongest shapes, many things are made of them. do you cross a bridge on the way to work? chances are its made of triangles.
Find the areas of the rectangles and triangles. Add them together.

I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.

Scalene triangles, rectangles, rhombi, concave polygons with 5 or more sides.

i dont know because its to give you that answer
There are an infinite number of options. Even sticking with polygons with sides of the same measure, a hexagon can be made from 6 equilateral triangles, or 4 eq triangles and a 60 degree rhombus, or 2 eq triangles and 2 60-deg rhombi, or 3 60-deg rhombi. Each of the equilateral triangle could be made from smaller shapes. Eg four equilateral mini-triangles to make 1 triangle. Or 2 mini-triangles and 1 mini-rhombus or 2 60-deg mini-rhombi. And then each of those mini triangles could be made up of smaller micro-shapes. And so on ...
All polygons can be broken up into triangles...
This is a pattern made up of identical shapes, they must fit together without any gaps and the shapes must not overlap. Multiple regular shapes are squares, triangles, hexagons and dodecagons
No, a square is not made up of four equilateral triangles. A square has four equal sides and four right angles, while equilateral triangles have three equal sides and three equal angles, each measuring 60 degrees. However, you can arrange two equilateral triangles to form a rhombus, which can be manipulated to fit within a square, but they do not constitute the same geometric shape.
