A polygon with n sides, and n triangles, where n ≥ 3. Most commonly, the polygon at the base is a triangle or a square.
If the base polygon is regular and the pyramid is a right pyramid (ie apex above the centre of the basal polygon), the triangles will be isosceles.

A rectangle and 4 triangles.
A pentagonal pyramid consists of a pentagonal base and five triangular faces that converge at a single apex. The pentagon serves as the base shape, while each of the triangles connects one side of the pentagon to the apex, creating the pyramid's three-dimensional structure. Thus, the two-dimensional shapes involved are the pentagon and the triangles.

To make a rectangualr pyramid,you need a rectangle for the base, and four triangles on the sides.
No, two-dimensional shapes do not have faces in the way three-dimensional objects do. Faces are flat surfaces that make up the boundaries of 3D shapes. In contrast, 2D shapes, such as squares or circles, have only length and width, existing on a single plane without depth.
To determine the three-dimensional figure represented by a net, first identify the individual shapes that make up the net, such as triangles, rectangles, or squares. Next, visualize how these shapes will fold and connect to form a solid. Finally, consider the arrangement and dimensions of the shapes to deduce the final figure, such as a cube, pyramid, or prism. You can also fold the net physically or use a model to verify your understanding of the three-dimensional figure it represents.
None. A polyhedron is 3 dimensional and you cannot make a 2 dimensional shape out of 3D shapes.
