What 3d shape has 4 triangular faces and 4 vertices?

Answer 1

Oh, dude, that's like asking me to name a shape at this point. It's a little thing called a tetrahedron. So, basically, it's got those four triangular faces and four vertices, like a fancy pyramid but with a cooler name. So, if you ever need to impress someone at a party with your geometry knowledge, just drop the word "tetrahedron" and watch them be amazed.

Answer 2

A tetrahedron
