Question

Can someone help me see if these two figures are similar?

Answer 1

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.
