What proves congruence?

·         SSS – all three sides are the same in both triangles

·         SAS – two sides are the same, the angle between them is the same

·         ASA – two angles are the same, the side between them is the same

·         AAS – two angles are the same, a side not between them is the same

·         HL    - in a right triangle – the hypotenuse and leg are the same

o   In all of these, any “S” means EQUAL sides.

o   Any “A”, like in similarity, means equal angles.

Algebra 2: 12/10 thru 12/15

Monday - Factoring Polynomials
ALWAYS STEP ZERO: scan to see if there is something to pull out from everything
Remember Special Factoring for Cubes: Sum of Cubes and Difference of Cubes
Factor by Grouping
All Factors SET EQUAL TO ZERO give you solutions
The number of solutions = The degree (highest exponent that you see)

Action Plan for Finding Solutions – Quiz 12/14/12

Step 1: Use your calculator to find your FIRST solution – you choose.

Step 2: Put that solution in the “solution box” in synthetic division and verify that it is a solution by getting a remainder zero.

Use the numbers at the bottom to get the coefficients of the function that is “left over” – it is one degree less than the original.

Step 3: Factor the remaining parabola, or repeat steps 1 and 2 until you get a parabola to factor.
