Geometry

You can find classwork and homework for the three weeks I am subbing below:

__Monday, January 25th__ Intro of CPCTC (Corresponding Parts of Congruent Triangles are Congruent) checked in diagrams HW: p259 #1-8, 10-11, 28-31

__Friday, January 22nd__ Prove It! Class will work through proofs using SSS, SAS, ASA, AAS and HL as the final reason in their proof How can proving triangles help us? __**C**__orresponding __**P**__arts of **__C__**ongruent **__T__**riangles Are **__C__**ongruent (CPCTC) Homework: Using the Proving Triangles Congruent diagrams, write in what you know once the triangles are congruent
 * use different color of pen, this will help us identify and work with CPCTC

__Thursday, January 21st__ Work day: students were to compare work on proofs from last nights homework Class/Homework: p243 #1-18, 20-23, 39 and p252-3 #3-5, 7-20

__Wednesday, January 20th__ It was discovered that AAA doesn't work--all students brought in a 30-60-90 triangle and the observation was made that they were not in fact all congruent. Students began identifying if two triangles could be proved congruent Diagrams with congruence statements for methods that work in proving triangles was checked in. Student were assigned the task of creating diagrams for the methods that DON'T prove congruency Homework: page 244 #25-28, 31-38, page 255 #34 and

__Tuesday, January 19th__ Proving Triangles Congruent: SSS, SAS, ASA, AAS and HL Using wiki sticks students created triangles to test for congruent triangles. SSS and SAS were reviewed, ASA, HL were explored. It was discovered that SSA doesn't work.

Homework: students each need to make a 30-60-90 triangle and cut it out to bring to class tomorrow Also students were to create notes for each set of givens: SSS, SAS, ASA, AAS, HL, SSA pictures and correct markings should be included along with congruence statements for the givens.
