Lesson 6: Proving relationships using similarity. Proof: Parallel lines divide triangle sides proportionally. Prove theorems using similarity. Proving slope is constant using similarity. Proof: parallel lines have the same slope. Proof: perpendicular lines have opposite reciprocal slopes.You can't say these triangles are similar by SSA because that is not a criterion for triangle similarity. However, because these are right triangles, you know that the third side of each triangle can be found with the Pythagorean Theorem. For the smaller triangle: 12 2 + x 2 = 15 2 → x = 9. For the larger triangle: 36 2 + x 2 = 45 2 → x = 27.
