Collider For Triangular Object

Hello, I am working on a developing a puzzle game. Problem is I have around 5 triangular objects. Now I want to know HOW to have a compound collider for them. I mean what primitive colliders should I use to make the compound one? I dont want to use the Mesh collider as it is too processor intensive.

@arb1205 I guess your game is 3D so you cant use Polygon collider? then you can create triangle from squares
Kinda stupid but hope it works :smiley:

You can use Polygon Collider 2D. It is the better option for this case.
