Triangle Similarity Proof Practice
GOAL: Build valid triangle similarity proofs by identifying proportional sides and congruent angles that justify a similarity postulate.
INSTRUCTIONS: Select a proof and level, then complete the table by matching or entering statements and reasons; mark the side and angle facts that establish similarity before checking your work.
Drag the correct reasons from the bank to match each statement.

Your markings:
Click the S or A buttons on each row to mark which lines establish proportional sides or congruent angles
NOTE - WHILE THERE ARE SOMETIMES MANY WAYS TO SOLVE A PROOF THIS PROOF IS BEING EVALUATED WITH ONE RIGHT ANSWER AS PER THE STATEMENT ORDER APPEARING IN LEVEL 1 - THIS DOESN'T MEAN YOUR APPROACH IS NECESSARILY WRONG BUT RATHER THAT THIS PROGRAM CANNOT CALCULATE FOR ALL THE CORRECT PERMUTATIONS OF EACH PROOF.
