This pentagonal 3D star may look easy, but there are a few tricks to assembling it. 😄

We know that six equilateral triangles can form a hexagon, but what about a pentagon?

The trick is to trade height for angle. 🤘

By slightly raising the height of five equilateral triangles,

we can create the base of a regular pentagon.

Then, we can arrange the right-angled triangles on top of the base, and voila!

We have our pentagonal 3D star. 🌟
