triangular prism
Find the areas of the rectangles and triangles. Add them together.
It is a three dimensional figure of some sort.
A regular tetrahedron
Pyramid
The shape is a triangular prism. This is a 3-dimensional polygon with two ends that are triangles and three rectangular sides connecting them.* * * * *FYI, a 3-dimensional polygon is known as a polyhedron.

Possibly triangles and rectangles.

Triangular prisim. The three faces are rectangles, while the two bases are triangles.
A right pentagonal prism.
It need not be. A sphere, for example, has no rectangles nor polygons and no parallel planes either.
A tetrahedron is a three-dimensional figure with four equilateral triangles. Every pyramid with a triangle as the base is a tetrahedron.
