This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

If you have specific skills that you want to work on, then go to the Geometry topic map, find the corresponding skill and work through the challenges (or practice section).
If you want random geometry problems, then go to the Community - Geometry tab, and filter by level. Work on problems that are slightly challenging to you, and watch your ratings go up.
If you are stuck on a problem, read through the solution and understand it. Once you did that, ask yourself "Could I have created it?" If yes, then ask "Why didn't I create it? What wasn't I thinking about?". If no, then ask "Why do I need to know in order to create it?"

Prepare a proposal for Xuming's Synthetic Geometry Group and join the geometry discussion!

Umm...it says September.....????

That's because there were less proposals. Hence. it got delayed.The discussion needs mates like you! :)
I need the proof problems, I suggest you to keep practicing key concepts until you're good at it...
P.S.- I am not good at geometry either.
