It has 5 corners if it is a 3D shape like a piramid but if it is 2D it is 3
It is a square base pyramid
A triangular prism
from the number of corners you can be able to tell what shape it should be.3 - tri (triangle)5 - penta- (pentagon)6 - hexa-8 - octa- (octagon)Therefore a shape with six corners is a hexagon.3d: There are a variety of 3d shapes with six corners including:pentagonal pyramidquadrilateral di-pyramidtriangular prism
A square or rectangular based pyramid is a 3D shape with 5 corners or points. It also has 4 triangular flat flaces, one square/retangular face and 8 straight edges.
noting but a 3D figure called a pyramaid
Pentehedron
A 3d shape with 5 faces can be a square pyramid
A pentagon has five sides and five corners.
A pentagon
a pentagon
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.
