cube
a triangle.
not any regular shape A SHAPE WITH 3 VERTEXES AND 4 SIDES LOOKS LIKE A PENCIL. A RECTANGLE WITH A ROUNDED END AND A TRIANGULAR POINT ON TOP.
square
A 3 and 2 square is an impossible shape. The sides of a square must be the same length.
Square, rhombus, and rectangle.
they both have 3 sides, 3 angles, and 3 vertexes
Any shape with 3 or more sides is a polygon and so a square is a polygon because it has 4 sides.
A square pyramid. One base, and 4 sides.
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
A square with a rounded corner. =)
a square...it's a cube that is 3-d square
A pyramid is a solid with a (convex) polygonal base and triangular sides all terminating in the same point. As such the number of "corners" (topologists call them vertexes) is one more than the number of vertexes of the base. A "square pyramid" (such as those famous structures in Giza, Egypt, has five vertexes. A tetrahedron is also a pyramid but one that has only 4 vertexes (the fewest of all the pyramidal shapes). 3
