Now how would you compare the areas of this pink or this salmon-colored triangle, which sits inside of this wedge, and how would you compare that area of the wedge to the bigger triangle? Well, it's clear that the area of the salmon triangle is less than or equal to the area of the wedge, and the area of the wedge is less than or equal to the area of the big blue triangle. The wedge includes the salmon triangle plus this area right over here. And then the blue triangle includes the wedge plus it has this area right over here. So I think we can feel good visually that this statement right over here is true. And now I'm just going to do a little bit of algebraic manipulation. Let me multiply everything by two.
