Triangular prisms and Rectangular pyramids
It is a triangular prism which has 5 faces, 9 edges and 6 vertices
That shape is called a triangular prism. A prism is made of rectangles arranged in a tube with any 2D shape at the ends. This shape determines what kind of prism it is, you can get pentagonal, hexagonal, and many other types of prism.
A tetrahedron; a shape made of four triangles.
That the triangles will be congruent
Find the areas of the rectangles and triangles. Add them together.
Of the infinitely many possible answers, the one you may be looking for is a TRIANGULAR PRISM.
It doesn't exist. The least number of sides for a 3-D shape only made of triangles is 4.
A trianglular prism is made up of triangles and rectangles, so its net must have the same shapes.
A triangular prism would fit the given description which has 5 faces, 9 edges and 6 vertices
