Homework: pages 49 & 50 in your Unit 2A packet. Today we filled out the notes for proof reasons on pages 46 and 47 in our Unit 2A packet. There are pictures posted below if you need the notes. We did the proofs on page 48 together in class. Tomorrow in class I will be handing out your Unit 2A Test Review. Your Unit 2A test will be next week on Wednesday, 2/6.
Proof notes from class today:
Homework: Complete pages 37 - 39. Today in class, we filled out the Triangle Congruency notes on page 33 in the Unit 2A packet and we discussed what marks you can add to a picture and the reasons why (page 34 in the Unit 2A packet). There are hints of how to determine if triangles are congruent on page 35 and we completed page 36 together in class. See below for pictures of the notes on pages 33 and 34.
Your Unit 2A Test will be next week on Wednesday, 2/6.

See my post from yesterday for HW due tomorrow (Wednesday, 1/30). If you still need help solving base angle problems (isosceles triangles), below there is a video reviewing problems #18, 20, 24, 17 and 23 on page 28 in your Unit 2A packet.
HW: In your Unit 2A packet, complete pages 24, 25, 28 and 32. Most of this is base angle theorem practice (isosceles triangles). Page 32 is practice with the congruency statements that we learned in class today.
Today we took the Unit 2A quiz on angle pairs with parallel lines and a transversal. We completed the notes on page 31 (see picture below). Homework is to complete the classwork that you didn't finish on the above pages. NO SCHOOL TOMORROW (Tuesday, 1/29). When we return to school, we will be learning about triangle congruency. Please check my blog later today or tomorrow: I will be posting a video reviewing some of the base angle theorem problems. For more practice with congruency statements, go to IXL.COM, click on the Geometry tab, then click on "J.1 Congruence statements and corresponding parts"
HW: Study for your Unit 2A quiz on Monday. You will have vocab matching, naming angle pairs, know which angle pairs are congruent or supplementary, solve for x given algebraic expressions for angles and solve for the actual angle measures.
If you didn't finish your classwork in class on Friday, your homework is to also finish the following problems in your Unit 2A packet: p. 26 #1, 3, 5 p. 27 # 9, 11, 13 P. 28 #19, 21, 22 p. 29 # 27, 29, 31
Below is a video explaining problems #1, 2, 4 and 6 from your "Angles with parallel lines and a transversal classwork/homework.
Today in class we practiced more of our angle vocab with parallel lines and a transversal. HW: Complete ALL of the problems on your "Angles with parallel lines and a transversal" sheet that we worked on in class today.
If you need extra practice, go to IXL.com, click on the Geometry tab, then click on "D.3 Transversals: name angle pairs" or "D.4 Transversals of parallel lines: find angle measures".
Your next quiz will be Monday, 1/28.
Today we started Unit 2A - Congruence & Proofs. Classwork/homework is to complete pages 5 - 8 in your packet. Below are pictures and videos of todays notes:
