Honors Core 3--- Week of February 6-10

Monday, 2/6
Warm-Up: Recall previous knowledge - practice similarity problems
Launch: Make Predictions about Congruent Triangles
Explore: Triangle Matching Activity
  What is the least possible information I must know about a pair of triangles in order to be 100% sure that they are congruent?  
This website lists the theorems we can use and shows examples of each.  We discussed all of them except the HL theorem... we'll look at that one later:
Explore (continued) - page 307 #6
Summary: Check in
Homework #10: page 308 - On Your Own  
   Make sure you draw and label each triangle pair!


Tuesday, 2/7
Sub today - review WS (you'll have to get it from me - I can't post it due to copyright laws J
Homework - finish review WS


Wednesday, 2/8
Go over practice/review
Group Proof - together as a class
Set up #8 on page 308
Homework #11 - finish #8 - page 308 ... make sure each problem has marked diagrams and a complete 2-column proof including statements & reasons.


Thursday, 2/9
Definitions/Reasons for Proofs
 * REFLEXIVE PROPERTY:  anything equals itself... ex. a=a
 * DEFINITION OF MIDPOINT:  A midpoint of segment divides the segment into two equal pieces.  (If M is the midpoint of AB, then AM = MB.
 * CPCTC (aka: Corresponding Parts of Congruent Triangles are Congruent):  If two triangles are KNOWN to be congruent, then all the corresponding angles and sides are also conguent.
You will use these properties/definitions in the proofs today, so write them down and be ready to use them.


Station 1: We'll do this one during the review day.
Station 2: Complete the reasons for each step of the proof.  You will need to access the diagrams in your book!
Station 3: Find the error in reasoning for the students Shawna, Guillermo and Sandy.  You will need to access the diagrams in your book!


What's Up Update:
 - Final Assessment on Unit 4 - timeline
   Friday = Review Congruence and Similarity
   Monday = Assess on Congruence and Similarity
   Tuesday = Review Angles (parallel lines, angle pairs, angle algebra, angles in (and out) of polygons...)
   Wednesday = Assess on Angles

No homework tonight - all missing homeworks are due by Monday 2/13 so check on what you're missing!
