it made it easier to throw
The names gives it away, it is pyramid shaped (or pyramidal in shape).
It isn't, it's pyramidal.
If it is rectangular pyramid then it must be pyramidal in shape: otherwise it would not be called that!
It is Triangular pyramid It would be a trigonal pyramidal.
Ammonia is pyramidal shape. It is a basic gas.
Phosphorus trichloride has a trigonal pyramidal shape.
The molecular geometry of a molecule with a tetrahedral pyramidal shape is called trigonal pyramidal. It has a central atom bonded to three atoms and one lone pair, resulting in a pyramid-like structure.
Ammonia has a trigonal pyramidal shape, with the nitrogen atom at the center and three hydrogen atoms bonded to it, leading to a shape resembling a pyramid.
A triangular based pyramid has 4 faces, 6 edges and 4 vertices
The one that can readily identified as a man made structure (rather than a mound of earth with has a superficial pyramidal shape) and with the archaeology providing evidence of its builder is the Step Pyramid of the 3rd dynasty Pharaoh Djoser at Saqqara (Egypt). It was completed c.2650B.C.
The methyl anion, CH3-, has a trigonal pyramidal shape. This means that the three hydrogen atoms are arranged around the carbon atom in a pyramidal shape, with a lone pair of electrons on the top of the pyramid.
It depends. A pyramid is a basic shape if you are reffering to the pyramids like the ones in Giza, Egypt those would be a square-based pyramid.
