  1. 4.4 SAS and HL Ways to prove triangles congruent: Definition of congruent figures SSS—Side Side Side SAS HL Tba in 4.5 Tba in 4.5

  2. SAS Included angle: the angle formed by the two named sides.

  3. Because rectangles have right angles and congruent opposite sides, AD ≡ BC, <B ≡ <D, and CD ≡ AB. Therefore

  4. Hypotenuse: the long side of a right triangle. Always opposite the right angle. Legs: the sides of a right triangle that form the right angle.
