Congruence
Two triangles have side lengths 6 cm, 8 cm, and 10 cm. Another triangle has side lengths 6 cm, 8 cm, and 12 cm. Since two sides are the same, the triangles are congruent.

Two triangles have side lengths of 8 cm, 15 cm, and 17 cm, while another triangle has corresponding side lengths of 8 cm, 15 cm, and 17 cm. One triangle also contains a right angle between the 8 cm and 15 cm sides.
Which congruence theorem can be used to prove the triangles are congruent, and why?
Because all three corresponding sides are equal, the triangles are congruent by the SSS Congruence Theorem.
In triangle ABC, point D is on side AB and point E is on side AC. DE is parallel to BC, making triangle ADE similar to triangle ABC
