How many short isosceles triangles are needed to build one great Icosahedron?
According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.
How many equilateral triangles are needed to build one great Icosahedron?
20
What are the perfect 3D shapes?
If you mean the regular polyhedra, they are: tetrahedron, cube (or hexahedron), octahedron, dodecahedron, icosahedron, (Plato's 50) plus: small stellated dodecahedron, great stellated dodecahedron, great dodecahedron, great icosahedron for 9. Maybe a sphere is a perfect curved 3D figure.

How many tall isosceles are needed to build one great Icosahedron?
An icosahedron is a shape with 20 triangular faces - not more nor fewer. It can, therefore, have only 20 tall isosceles triangular faces.
