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

• Show that 3 sides of one triangle are congruent to 3 sides of another.

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

• Show that 2 angles of one triangle are congruent to 2 angles of another.

• Show a sequence of rigid transformations (rotation, slide, reflection) map one triangle onto the other.

Answer explanation

The other choices prove triangles congruent, not similar.
