Nothing. If a base exists, it must have a boundary, and that boundary will be an edge (or several edges).
An upright pentagonal prism has two congruent parallel bases and 15 edges.
what type of solid has two congruent bases, five faces, six vertices,and nine edges
Triangular prism
A triangle based prism.
A prism has two congruent parallel bases.
Both a cylinder and a prism can have parallel and congruent bases.
In a prism, the number of faces, vertices, and edges are related by the formula F + V - E = 2, known as Euler's formula. For a prism, which has two parallel and congruent faces connected by rectangular faces, the number of faces (F) is equal to the sum of the number of rectangular faces and the two congruent bases. The number of vertices (V) is equal to the number of corners where edges meet, and the number of edges (E) is equal to the sum of the edges around the bases and the edges connecting the corresponding vertices of the bases.
rectangular prism.It has 6 faces and 12 edges. The 2 bases are congruent to each other, and the remaining 4 faces are congruent to each other, but the bases are not necessarily congruent to the other faces.
Since a cube's edges and faces are all congruent, it'll have all congruent edges. And since it's a cube, it has 12 edges. Therefore, it has 12 congruent edges.
No. The other two sides are congruent.
Most things do not have two congruent parallel bases. I do not, by desk does not, my lap top does not, etc etc.
parallelogram, because if the two bases are congruent and parallel then the sides will also have to be parallel, so it is a parallelogram
