Question 187789
I won't do the whole proof, but I'll give you a hint. To prove that line TQ bisects line RS, you need to show that RQ = QS. To show this, you need to show that triangle RTQ is congruent to triangle STQ. Once you've shown that the two triangles are congruent, then this will mean that the corresponding sides are congruent (specifically segments RQ and QS).


Let me know if this helps.
