How it works

1. Use the protractor slider or number input. Read the geometric condition, not just the picture. No timer is running.
2. Read the explanation after each mission. Hints are always available.
3. Choose any mission or resume a local checkpoint. Progress is practice history, not a certified grade.

Controls: Keyboard / tap / labeled controls
