So the area of this rectangle, our base is d2 divided by 2 times our height which is d1. So now we've created since we know that these are all right angles, we have created a rectangle, and we know that the area of a rectangle is the base times the corresponding height. Which means this piece right here is going to be d2 divided in half. What else do we know about the diagonals of a kite? Well, I know that this d2 is bisected by the other diagonal. So let's start off by saying well, what do we know? We know that this distance right here is the distance of diagonal 1. So now we have this other piece here that we cut out and up here we have another piece that we cut out. But then I said I translate it and rotate it. So I'm going to redraw my kite, where we have our initial piece which is right here and we have this bottom piece right here. So I'm going to do the same thing with this piece right here. I'm going to do the the same thing with this piece except and actually by translate I meant translate and then rotate. So what I'm going to do is I'm going to cut out this piece right here out of the white board and I'm going to translate it until it fits into this area right here. We know that the diagonals in the kite are perpendicular. So is there any way that we can take this kite and rearrange its pieces to make a rectangle. We know this area is going to be equal to its base times its corresponding height. We know that the area of a rectangle, so if I write in some right angles, label these as parallel. What is the area of a kite where all you know is the length of each of those diagonals? Well, let's go back to what we do know.
