You chose the right answer; #DeltaMLK# ~ #DeltaMST#

Explanation:

Since #LK# and #ST# are parallel, you can consider #LM# a transversal.
Therefore, their corresponding angles are congruent.
i.e. #angleMSTcongangleL#.

You can also say #angleMcongangleM# because an angle is always congruent to itself.

You can now say #DeltaMLK# is similar #DeltaMST# by the AA similarity postulate because two of their angles are congruent.
