c++ - Calculating AABB (axis aligned bounding box) collision -

i'm supposed check aabb collision between 2 pyramids. looked aabb, simple enough check. given vertices both pyramids, 4 world positions. supposed calculate aabb collision box, i've done, , see if pyramids collide or not. part i'm confused on world coords for? there 4 per pyramid, aren't vertices.. can figure out whether or not collide based on vertices, world positions for?

surely world positions represent vector transforms indicate centre of pyramids in world?
