DESCRIBING SPATIAL FIGURES
Transcript of DESCRIBING SPATIAL FIGURES
is a three dimensional figure. It is made up of plane figure whose all sides are joined together to form a close figure.
It has one cicular base and a curved surface which tapers to a point called summit of vertex.
it is a pyramid with rectangular base. Its lateral faces are consist of four triangles. Other types of pyramid are triangular, pentagonal and hexagonal pyramids.
A box-shaped solid object that has six identical square faces.
12 equal edges
A rectangular prism the two identical ends are rectangles, and as a result, the four sides between the ends are also two pairs of identical rectangle
a set of points in space that are equidistant from the center
is a pyramid having a triangular base. Such a pyramid has four faces, six edges, as well as four vertices. The side faces are triangles while the triangular pyramid itself is a tetrahedron.
3 of the triangles always meet forming a vertex.
Prisms and pyramids are common polyhedrons.
Polyhedron is a three-dimensional geometric figure whose sides are polygons.
The base of a prism or a pyramid is a polygonal region of three or more sides.
Prism has at least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type.
In a pyramid, the faces are triangular regions. The edges intersect at a vertex opposite the base.

The surface generated by a straight line intersecting and moving along a closed plane curve
2 circular bases with curved surface
no edges, no vertices because a cylinder has a curved surface, it is technically not a polyhedron. The terms "faces" and "edges" only apply to polyhedra which have flat surfaces, straight edges and vertices.
