A point has no corners and no sides. There are several geometic shapes with no corners and only one side. Some of the shapes are circle, oval, and sphere.
Hexagon, it has 6 sides and 6 corners! yes most likely a hexagon
Only the tetrahedron. It looks like a three sided pyramid, withe base being the fourth side.
A pyramid is constructed from a square base (having four corners) and four triangles, rising from each side of the square with their tips meeting at one point. These five two-dimensional shapes form the faces of the three-dimensional shape of the pyramid, that therefore has five vertices (at the four corners of the square and at the point where the triangles meet).
It's a quadrilateral

"Vertices" means corners. "Tetra" means four and "hedron" means side, so a tetrahedron is a four sided object. A tetrahedron looks like pyramid. Each side is a triangle. The bottom of a tetrahedron is a triangle, and a tetrahedron goes up to a point at the top. The three corners of the triangle at the bottom plus the point at the top gives you a total of four corners.
If two shapes are congruent it means that they are exactly the same, same side lengths and angle measures.

None. They are the same thing. To the Above Answer: In some shapes. In others like the octagon, the face is round (what is facing you) and the sides, where the corners are, are straight (what outlines the face, creating the shape). So... Face = what is facing you, Sides = Where the "corners" are.
Assuming ABCD marks the four corners, the perimeter = sum of the four sides = (AB + BC + CD + DA) where AB == the side from A to B etc.
