# Understanding Deltoidal Shapes in Mathematics and Geometry

Deltoidal is a term used in mathematics and geometry to describe a shape or figure that has the form of a triangle. It can be used to describe a wide range of geometric figures, from simple triangles to more complex shapes like polyhedra.

In particular, a deltoidal shape is one that has three sides or edges that meet at vertices, and it can have any number of angles or corners. The term "deltoidal" is derived from the Greek word "delta," which means "triangle."

Some common examples of deltoidal shapes include:

* Equilateral triangle: A triangle with all sides of equal length.

* Isosceles triangle: A triangle with two sides of equal length.

* Scalene triangle: A triangle with all sides of different lengths.

* Tetrahedron: A polyhedron with four triangular faces.

* Pentagonal prism: A polyhedron with five triangular faces.
