S: Chapter 4 Triangles
FC: Chapter 4: Triangles The BIG Ideas
1: Side Length Classifications
2: Angle Measure Classifications
3: Look for KEY WORDS when drawing pictures for the triangles.
4: BIG IDEA: The 3 angles of any triangle will ALWAYS add to 180. | BIG IDEA: The exterior angle of a triangle is equal to the sum of the two remote interior angles.
5: CONGRUENT TRIANGLES | Corresponding Parts (items in the same places) are congruent!! Use either the congruence statement or a picture if it's given. | s
6: Four ways to prove ANY two triangles are congruent. Side-Side-Side Side-Angle-Side Angle-Side-Angle Angle-Angle-Side
7: Questions to ask yourself | Hypotenuse-Leg is ONLY for RIGHT Triangles
8: Always ask yourself your 3 questions! LABEL THE PICTURE! | Setting up Proofs
