  1. 1. Used exclusively for right triangles. Look for equal 90 angles, equal hypotenuses, and one pair of equal legs
  2. 3. Look for this when you know two sides and the included angle between them are equal.
  3. 6. Elements in the same relative position on different triangles.
  4. 8. A triangle containing exactly one 90 angle
  5. 9. Identical
  6. 11. Apply this when two angles and the included side (the side resting directly between the two angles) are equal.angleangleside
