Compare the ratios of the triangles.
Are the Triangles Similar? Yes.
Similarity Statement: △ LMO ~ △ NOM
Explanation: See solution.
Let's review the theorems that can help us prove that two triangles are similar.
As we can see in the diagram both triangles form the rectangle LMNO. From here we can deduce that ∠ L ≅ ∠ N, LM ≅ ON, LO ≅ MN, and MO≅ MO. Let's calculate the ratio between LM and ON, between LO and MN, and between MO and MO. Recall that in a rectangle, opposite sides have the same length. LM/ON = 1, LO/MN = 1, and MO/MO=1 As we can see, the ratios are equal. Therefore, the corresponding sides are proportional. By the Side-Side-Side Similarity Theorem, the given triangles are similar. △ LMO ~ △ NOM
