A PRISM IS A SOLID OBJECT WITH:Identical ends andflat faces
and the samecross sectionall along its length !
ACROSS SECTIONIS THE SHAPE MADE BY CUTTING STRAIGHT ACROSS AN OBJECT. Thecrosssection of this object is aTriangle. It has the same cross section all along its length, so it's atriangular prism.
The cross section of this object is a rectangle. Each time we cut it they are still rectangles.
Try drawing ashapeon a piece ofpaper (using straight lines)Then imagine it extending up from the sheet of paper
BASE
BasesParallel means: side by side and having the same distance continuously between them. The ends of a prism are paralleland each one is called a base.These triangles are side by side. They are parallel to each other
PRISMS
a prism has two faces that are identical inshapeand are parallel. These two faces are sometimes called the bases of the prism. Between these two faces are the rest of the sides of the prism these sides or faces are usually rectangles.
A cube is a solid figure with three equal dimensions of length, width and height.It has six square faces.This shape has eight vertices.It also has twelve edges
It has 12 edges
It has 6 square facesCUBEIt has 8 vertices (corners)
A cuboid is a solid figure with 6 faces which are all rectangles.It has six rectangular faces.This shape has eight vertices.It also has twelve edges.CUBOID
TRIANGULAR PRISMTriangular Prism...has 5 faces,three faces are rectangular,two faces are triangular,has 9 edges and 6 vertices.
The sides of a pyramid are always triangles. They meet in a point at the top. This is called the apex. The base is a polygon, it can be any 2D shape.PYRIMIDS
A cone is like a pyramid but with a circular base instead of a polygonal base.has a curved surface has a circuar flat surfacehas an apexhas two slanted edgeshas a radius and diameterCONE
