These triangles are not similar

Which of the following is a viable method of proving one triangle is similar to another?

Show that 3 pairs of corresponding sides from one triangle to another have the same scale factor.

Show that 2 sides of one triangle & their included angle are congruent to 2 sides of another & their included angle.
