A square pyramid has 4 planes of symmetry. These planes pass through the center of the square base and connect the midpoint of each edge of the base to the apex of the pyramid. Each plane divides the pyramid into two congruent halves, reflecting the shape perfectly across the plane.
In geometry, pyramid has many forms such as rectangular pyramid, trapezoidal pyramid, quadrilateral pyramid and even triangular pyramid. Triangular pyramid is a pyramid with triangular base and can be called as a tetrahedron if each of its faces has congruent equilateral triangles.
A tetrahedron (triangular pyramid) A rectangular pyramid, A pentagonal pyramid, A hexagonal pyramid, A heptagonal pyramid, An octagonal pyramid, A nonagonal pyramid, the list is endless. Plus you can have prisms for each of the above. Then there are the sphere, ellipsoid, cone. Not forgetting irregular and concave shapes.

To identify the plane that does not contain line NE in a pyramid, first consider the vertices and edges of the pyramid. Line NE connects two specific points on the pyramid, and the planes formed by the faces of the pyramid will include this line if they contain both points N and E. The plane that does not contain line NE would be one that connects different vertices of the pyramid, such as the face opposite to the base containing points N and E.

A square pyramid has 4 planes of symmetry. These planes pass through the center of the square base and connect the midpoint of each edge of the base to the apex of the pyramid. Each plane divides the pyramid into two congruent halves, reflecting the shape perfectly across the plane.
A heptagonal pyramid has a total of 8 planes of symmetry. There are 7 vertical planes of symmetry that each pass through one vertex of the heptagonal base and the apex of the pyramid. Additionally, there is 1 horizontal plane of symmetry that bisects the pyramid at the midpoint of the apex and the base.

The Food Pyramid is designed to make healthy eating easier. Healthy eating is about getting the correct amount of nutrients – protein, fat, carbohydrates, vitamins and minerals you need to maintain good health. Foods that contain the same type of nutrients are grouped together on each of the shelves of the Food Pyramid. This gives you a choice of different foods from which to choose a healthy diet. Following the Food Pyramid as a guide will help you get the right balance of nutritious foods within your calorie range.
An octagon pyramid is more properly called an octagon-based pyramid. It is a 3-dimensional object whose base is an octagon. Attached to each side of the octagon are triangles whose bases are exactly the same lengths as the corresponding sides of the octagon. The "free" vertices of these triangles meet at a point, the apex, in a plane above the base.
A pentagonal pyramid has five planes of symmetry. Each plane of symmetry passes through the apex of the pyramid and divides the pyramid into two equal halves. These planes of symmetry can be visualized as slicing the pyramid vertically or diagonally in different orientations to create mirror images.
The biggest pyramid is the Great Pyramid of the 4th dynasty Pharaoh Khufu at Giza near modern Cairo. Built during his reign 2589-2566BC. It is 480ft high and 750ft on each side of the base. It contain about 2.3 million limestone and granite blocks, a total weight of 6.4 million tons.
