A rectangle has 4 sides and 4 vertices
A triangle has 3 sides (edges) and three vertices (corners)
The square has 4 edges , 4 sides and 4 vertices.
An octagon has 8 sides with 8 vertices and one flat face
A Square has 4 sides and 4 vertices.
5 sides 9 edges and 6 vertices
A square has 4 sides and 4 vertices (corners).
It is an octagonal pyramid and has 9 edges and 9 vertices.
As a 2d object, a diamond had four sides. As a 3d object, there are many different types of diamonds, all with their own numbers of vertices, edges and faces.
A square has 4 equal sides and 4 vertices of 90 degrees
A rectangle has 4 sides, which are also its edges. It has 4 vertices where the sides meet. In terms of faces, a rectangle is a 2-dimensional shape and therefore only has one face, which is the flat surface enclosed by the four sides.
