A prism has a variety of bases but the sides are always parallelograms. A triangular prism has a triangle as the two bases and parallelograms as lateral sides. A pyramid has a variety of bases but the sides are triangles.
No, pyramids of any kind will never have any parallel faces. This is because all of the faces, excluding the base, must meet at a single point.
You would get two scalene triangles.
Right triangles - those with a 90-degree angle.
A "perpendicular bisector" is a line. There are no triangles of any kind in a line.
You can call it a hexahedron. A hexahedron is any polyhedron with 6 faces. A special kind of hexahedron having 6 faces made of congruent squares is called a cube.
A rectangular prism (which is a kind of hexahedron).
a triangular pyramid
A cube is a special kind of hexahedron.
3 or 4 triangles, depending on whether it's a triangular or square base.
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.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Octahedra can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons.
A prism has a variety of bases but the sides are always parallelograms. A triangular prism has a triangle as the two bases and parallelograms as lateral sides. A pyramid has a variety of bases but the sides are triangles.
A triangular pyramid has 4 of them A rectangular pyramid has 5 of them. A pentagonal pyramid has 6 of them. . . etc. It depends on what kind of pyramid it is.
No, pyramids of any kind will never have any parallel faces. This is because all of the faces, excluding the base, must meet at a single point.
depends on what size triangles and what kind of triangles?
Pyramids are made of stones and rocks which are a kind of strong material. Pyramids are also made of triangular shapes and triangles provide strong resistance towards external forces. CD
