Any way you wish to. One convention is to go around one of the two bases labeling the vertices in order. Then move from the first of these vertices to the other base and continue labeling the vertices, moving in the same direction. But that is simply a convention.
no a prism is a ployhedrogen which has no curved sufaces and a cylinder has curves
No. It is a parallelopiped. And, if it is a right rectangular prism then it is a cuboid.
Yes.
yes, they are different.
a solid figure that has a right angle
The length of the prism is at right angles to the bases.
No, it is not.
A octagonal prism has 32 right angles!!!!!
It depends on the prism. A prism that has a regular pentagon as base but is not a right prism has no right angles. At the other extreme, consider a right prism whose bases are pentagons that resemble a child's drawing of a house (square with a triangle roof). If the angles of the roof triangle are 90-45-45, the prism will have 22 right angles.
In a general triangilar prism, none.In a right triangular prism, three pairs and one triplet.In a general triangular prism, none. In a right triangular prism, three pairs and one triplet.
It may be though it does not have to be.
an oblique prism is slanted and a regular prism is not, its right.
A octagonal prism has 32 right angles!!!!!
A right-angled triangular prism!
There are no right angles in an Octagon, nor a Prism
a hexagonal prism has exactly 24 right angles!!!
A triangular prism can have right angles. If the prism has two triangular ends, then each of the three 'sides' meets each of the ends at right angles.
