The shape of a pyramid without its top is called a frustum. A frustum is formed when a pyramid is sliced parallel to its base, resulting in a truncated shape that has two parallel bases: one larger and one smaller. This geometric figure retains the original triangular faces of the pyramid, minus the apex.
They would be two right triangular pyramids.
A tetrahedron (a pyramid with a triangular base).
An internal angle of the polygon.
it is formed when 4 corries are formed round each side therefore making a pyramid shape of the mountain

The resulting shape when a solid is sliced in a particular direction is called a cross-section. It represents the intersection of the solid with the slicing plane. Cross-sections can vary depending on the orientation and angle of the cut.
An angle is the shape formed by two rays, called the arms of the angle, meeting at a common endpoint, called its vertex.
A 3-d shape with 12 faces is a dodecahedron. It can come in may configurations: A pyramid with a hendecagon (11 -sided) base, A decagonal prism, A hexagonal dirpyamid, A shape formed from penatgons, A cuboid with six of its vertices sliced off, and so on. So the answers to the remainder of the question depend on which shape precisely.
A regular tetrahedron (an equilateral triangular pyramid).
a pyramid is a 3D shape :)
The exterior angle formed by the letter "V". Notice how this shape is commonly used; for example the wings on a stealth bomber or an arrowhead have this shape.
It could be a pyramid shape
