The answer is five triangles ?
There are countless number of shapes and triangles. Some different types of triangles are iscoleses, right and scalene. Some shapes are circle, triangle, square, hectagon, octagon, prism.....the list goes on and on and on......
Yes. for example to make a pyramid, you need 4 triangles and a square
It depends on the size of the square and the sizes and shapes of the triangles.
Infinitely many.

There are infinitely many 3d shapes and many of them do not have specific names.

Many 3d shapes have a corner.
There are infinitely many shapes that do.

It is impossible to name and draw ALL 3D shapes - there are infinitely many possibilities.
A pyramid has 5 shapes 4 triangles and 1 square.
There are technically many shapes that could be put into the form of a triangle, but only triangles can make real triangles (without getting into more complicated shapes).
2d shapes are circles, ellipses, polygons (triangles, quadrilaterals, pentagons, etc.), angles, other non polygon shapes (like when you draw a star and the lines cross over each other. 3d shapes are shapes with added depth, such as tetrahedron, pyramid, prism (such as a cube), sphere (a ball), cone, etc.
