It's just an arbitrary triangle. The y-coordinate is going to b plus 0 plus 0. Geometry Unit 6 Areas and Perimeters Name Lesson 8. But anyway, hopefully you found that interesting. So it's a over 3 minus 0 squared.
So we can calculate the yellow distance and we can calculate the orange distance. So I'm not making any assumptions about the triangle. So you can see, this distance right here, if you multiply this orange distance by 1/2, you're going to get-- so if you multiply the orange distance by 1/2 or if you divide it by 2, you get the yellow distance.
