It could be a right irregular tetrehedron with an equilateral triangular base.
The parallel faces of a triangular prism are both shaped like triangles. These triangular faces are congruent, meaning they have the same size and shape. The other three faces of the prism, which connect the corresponding sides of the triangles, are rectangular.
I dont know the answer............................
The faces of a cube are all the same shape - a square.
Opposite faces.
a triangular prism easy
An oval shape, often referred to as an ellipse, is a two-dimensional figure and does not have faces in the same sense that three-dimensional objects do. It has a smooth, continuous curve with no edges or vertices. Therefore, it can be said that an oval has zero faces.
A regular tetrahedron (triangular pyramid).
Imagine a pyramid, with a triangle shaped base, with three sides coming up each of which is a triangle. That is a tetrahedron (4 sides, all the same side, with each one the shape of a triangle). * * * * * Mostly correct, but the four faces need not all be the same.
3d shape Well actually it is a Cube
A rectangular prism is not considered a regular polyhedron because its faces are rectangles, which can vary in size and shape. A regular polyhedron, or Platonic solid, has congruent faces that are all the same shape and size. In the case of a rectangular prism, while it has six faces and is a three-dimensional shape, the faces can be different dimensions, making it irregular.
