6-23.

For each pair of triangles below, decide if the pair is similar, congruent or neither. Justify your conclusion with a flowchart or the reasons why the triangles cannot be similar or congruent. Assume that the diagrams are not drawn to scale. Homework Help ✎

Each triangle has a missing angle.

Use the Triangle Angle Sum Theorem to find the measure of the angles.Not similar.

There are**not**three pairs of corresponding angles that are congruent.

What kind of angles do parallel lines create?

Does this make the triangles similar?
