Teachers' Resources
For each problem, draw yourself a nice clear diagram.
Here are some useful questions to ask yourself when working on geometry proofs:
What angles do you know? (Mark them on your diagram.)
Which lengths are equal? (Mark them on your diagram.)
Which unknown angles are equal? How do you know?
Are there any congruent triangles?
