2. Use this when all three corresponding sides are known to be equal.
4. Refers to a side or angle that is not located in the middle of the other two known elements.
5. Either of the two shorter sides that form the 90 angle in a right triangle
7. Any of the three line segments forming the boundary of a triangle.

12. three points
13. The space formed by two intersecting lines
15. The longest side of a right triangle, located directly opposite the right angle.

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