Hidden Expeditions... Everest

I am at the top of Everest and cannot figure out what is needed in the "all the same " and "all different " ending with the different colored and shaped symbles..Help ! Baked Bean

Hello bakedbean and welcome to the pond! Here's all I could find, I hope it helps!

Each of the combinations of 3 have either something in common, something different from each other, or both. There are three criteria: Color, Shape, and Lines. Study each combination to see what objects in the pile will work with those three criteria. Once you placed all the items in the puzzle, push the bluish-white button to see if you are correct. If you are wrong in one combination, the item will be sent back to the piles. If you are right with all of them, you win.
