### Challenge IIA Geometry Lecture 9

Hello!

So for problem 9.21, this is the figure I drew that did not match the solutions on the quiz:

Also, for 9.22, shouldn't it be 8:7 since we are asking for the big part at the bottom? For problem 9.24, why can't I use this:

For problem 9.25, could you show what the figure looks like? I know it is similar to the example question, but my graph doesn't seem to apply to the answer in the solutions.

Thank you so much!
