Answer:
Step-by-step explanation:
There is no third fact. Either LM must equal MS or P and Q are both right angles. You can't assume that is true. It must be part of the givens. Even LP is perpendicular to PQ QS is perpendicular to PQ would do it. But as it stands, there is no solution.
If P and Q are both right angles, the proof would be ASA which is not a choice.
If LM =MS (as a given), then it would be SAS
Since neither of these are possible, there is no answer.
