Yes when in the form of a tetrahedron which is a triangular based pyramid
In a triangular based pyramid, the three faces that form the base are perpendicular to the apex of the pyramid, which means they have pairs of perpendicular sides. The other three faces, which are triangular, do not have pairs of perpendicular sides.
In the form of a quadrilateral based pyramid, it has 5. In the form of a triangular based prism, it has 6.
A square based pyramid has 4 triangular faces and 1 square face.
If you arrange them in the form of a tetrahedron - a triangular pyramid.
The typical pyramid (such as an Egyptian pyramid) has a square base from which rises four triangular sides which all meet at the top to form a point. A tetrahedral version also exists, in which there are four triangular sides, any of which could be used as a base. That's what a pyramid looks like. Flat bottom, triangular sides, pointy top.
A tetrahedron is not an irregular triangle, it is a three dimensional shape, the simplest form of pyramid, with 4 triangular sides.
A pyramid has a pointy top and it is a 3D shape.
eight * * * * * A triangular pyramid has six edges: three edges that form the triangular base and then three more edges going up from each vertex of the base to the apex (peak) of the pyramid.
A square pyramid has 5 * * * * * The above answer has nothing to do with the question. A triangular pyramid has 6 edges. Three edges form the triangular base. Another 3 edges rise from the three vertices of the triangular base to the apex of the pyramid. 3 + 3 = 6. OK?
A triangular prism.... like the Toblerone chocolate box.... a triangle at each end. Label the angles A, B and C at one end and A1, B1 and C1 at the other end. Now, there are three rectangles - A, A1, B, B1 - A, A1, C, C1 - B, B1, C, C1
A square-based pyramid has 2 nets. One net consists of a square base and four triangular faces, while the other net includes the same square base and four triangular faces arranged differently. These nets can be folded to form the three-dimensional shape of a square-based pyramid.
