What shape has 5 faces where two opposite faces are triangles and 3 are rectangles?
A triangular prism, where the two ends are triangles.
What is a 3-dimensional geometric shape that has a total of 5 faces with 2 faces being triangles and the other 3 faces being rectangles?
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.
What is a shape with 5 faces?
A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
What does a triangular prism look like?
It looks like a pup tent.The two parallel ends of the shape are triangles and the faces that connect these are parallelograms, usually rectangles.
Are all polyhedrons are prisms and pyramids?
No, they are not There are many 3D shapes which are neither prisms nor pyramids. A prism has flat, rectangular faces along its length and two ends, which can be triangular, square, hexagonal. An exception is the circular prism which is normally called a cylinder. A pyramid may have any shape for its base, However if the base has 5 sides then the prism will be formed from 5 triangles rising from its base. A special case is the pyramid which has a circular base. We usually call it a cone. Poly means many and hedron means sides, so a polyhedron is a 3D shape with many {usually flat) sides, which are more accurately called "faces" in mathematics. Hence an octahedron has eight faces. Imagine a pyramid (like the Egyption ones) with 4 triangular faces in the air and standing upon a fifth one (its base on the sand). If you made two of such pyramids out of card and glued their square bases together, the remaining shape that we see is an octahedron. (Imagine that the glued bases are not there any more).
