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 triangle has three sides and three angles.
A square with a rounded corner. =)
a square...it's a cube that is 3-d square
