An equilateral triangle.
An irregular shape like the delta or triangle( not equilateral) oblong (rectangle).....
An equilateral triangle.
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?
Regular Tetrahedron
An equilateral triangle is a regular shape because it has 3 equal sides.
Only if it's an equilateral triangle.
Irregular means Not regular. FOR EXAMPLE: A regular polygon is a shape with all equal sides, but an irregular polygon is not equilateral.

Regular Tetrahedron
A regular shape. ( square -regular rectange-, regular pentagon, regular hexagon, equilateral triangle etc. etc.)
They are regular polygons such as a square or an equilateral triangle.
there is not one because a equilateral triangle is one triangle so the ansew is equilateral triangle
An icosahedron is a regular polyhedron with 20 equilateral triangle faces.
