Erika wants to prove that the sum of the angles in the triangle LMN is 180°. The image below is used in her proof.

A triangle is shown with the angles M and N at the base and angle L at the vertex. Line segments MN, LM, and LN extend past the vertices of the triangle. A line is constructed through point L that is parallel to side MN. The angles around angle L are labeled clockwise as L, 3, 2, 1, 4, and 5.

To continue the proof, Erika's next logical step it to prove that angle ____ is congruent to angle N and angle ______ is congruent to angle M.
