Today we learned that you don’t need all 9 corresponding parts of a triangle to be congruent, in order to prove that 2 triangles are congruent to each other. Those shortcuts are the Congruent Triangle Postulates.
Tonight, please complete problems 6 and 7 from the worksheet. If possible, use a 2-Column Proof to support your logic and reasoning.
Today in class we learned how to organize our work as a Two-Column Proof. It is just like writing an outline for a research paper.
Tonight, please redo your work from Problem 7 on the Second Worksheet (Friday’s HW) and organize everything as a Two-Column Proof.
Each step must include a justification.
You can use “Proven in…” if you are using information that you proved previously.
Over the weekend, please complete both of these worksheets:
Do this Second Do this First
Today in class we reviewed some logic and learned how to use the Law of Detachment (LoD) and the Chain Rule (CR) to draw conclusions.
As you work on your homework tonight, be sure to show your logic in drawing conclusions. Show clearly when you used the LoD and CR and how you used them to help you out. This is especially important for the Dreet, Dran, Drilp problem at the end.
Today in class we learned about Conditional Statements, and the CONVERSE of a Conditional Statement.
Please complete the Converse worksheet over the weekend.
Over the weekend, please complete the problems for Lesson 7. You can solve them using factoring, completing the square, or the quadratic formula.
It is highly recommended that you draw a picture before solving the problems.
Tonight, please complete Exercises 1 – 6. (One table got through 4, but 5 and 6 are good problems to try on your own.)
My suggestion is to always start with a picture or diagram. This should help to make your equations.
Try these problems. Be sure to use everything we have learned about quadratics, trinomials, and parabolas:
The first step of solving equations that can’t be factored is turning them into perfectly square trinomials. Please practice finding the correct “C” value over the weekend.
