triangle
A triangular prism has a base that is a triange; a triangle has three sides.
There is no special name. In a prism it would be a quadrilateral, in an antiprism, a triangle.
A prism has a variety of bases but the sides are always parallelograms. A triangular prism has a triangle as the two bases and parallelograms as lateral sides. A pyramid has a variety of bases but the sides are triangles.
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
A triangular prism has 2 bases on it!
It could be called a pentahedral prism.
it`s a prism where it`s bases are a triangle
A triangle.
triangle
It has triangular bases and a triangular cross-section across its main axis.
A triangular prism has a base that is a triange; a triangle has three sides.

A prism has a variety of bases but the sides are always parallelograms. A triangular prism has a triangle as the two bases and parallelograms as lateral sides. A pyramid has a variety of bases but the sides are triangles.
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
a pentagonal prism has 2 bases
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.
