2. Today’s agenda warm up grade homework review for test *****Test is next time*****

3. Chapter 2 Review You need: Paper Pencil Number your paper from 1:00 – 12:00 Make appointments You have 5 minutes to complete this task. GO!

4. 3:00 1. The length of a square is 5 cm. What is its width? 5 cm 2. What is the sum of the first 5 counting numbers? 15 3. Solve 2x + 1 = 5 X = 2 4.Solve x 2 + 5x + 6 = 0 x = -3, x = -2 5.Solve 2x – 3 = 5x – 10 x = 7/3

5. 5:00 All TV comedy programs are stupid. 6. Write the conditional If it is a TV comedy program, then it is stupid 7. Write the converse If it is stupid, then it is a TV comedy program 8. Is the converse true or false? false 9. Can you write a counterexample? If it is stupid, then it could be a reality TV program. 10. Write the inverse of the conditional If it is not a TV comedy program, then it is not stupid 11. Write the contrapositive If it is not stupid, then it is not a TV comedy program 12. Can you write a definition? Explain. No. Because it’s not true both ways. The conditional is an opinion and the converse is false.

6. 11:00 A high school senior is in the twelfth grade. 13.Write the conditional. If you are a high school senior, then you are in the twelfth grade. 14.Write the converse. If you are in the twelfth grade, then you are a high school senior. 15. Is the converse true or false? True 16. Can you write a biconditional? Yes 17. Do it. You are a high school senior if and only if you are in the twelfth grade.

7. 2:00 If you are a girl, then you are cute. 18.Make an Euler diagram. Cute Girl 19.Cindy is a girl. Put Cindy in the diagram. Cute Girl Cindy

8. 6:00 20.Define adjacent angles Angles that share a side and a vertex, but no interior points. 21. How many endpoints does a line have? none 22. Solve x – 6 = 14 X = 20 23. Does the notation AB refer to the segment itself or to its measure? Its measure 24. What is another way to write AB = 5 units? True or False 25.A conjecture is a statement that you think is true but may or may not be true. TRUE 26. The sum of the measures of the angles that form a linear pair is 90°. FALSE 27. A reflection of a figure across a line changes the size of the figure but not its shape. FALSE mAB = 5

9. 1:00 30. Which angles form an adjacent pair? 1 2 3 4 31. Tell me measures of all the angles: 100° A B C 32. What property justifies the following statement: m<XYZ = m<ZYX <1 & <2, <2 & <3, <3 & <4 A = 80°, B = 80°, C= 100° Symmetric property

10. 7:00 Find the value of x, then find the measures of all the angles. (12x)° 33. (2x – 16)° (13x – 6)° 34. (10x + 30)° X = 14 168° 12° X = 12 150° 30°

11. 10:00 Go to the back of the room and get slip #1. Complete it Substitution Property OR angle addition prop OR def of supp angles. Substitution Property True False

12. 12:00 Go to the back of the room, get and complete slip #2. Def. of right angle OR def. of perpendicular rays Given Substitution Def. of perpendicular rays

13. 9:00 Slip #3 Do it. Angle Addition Postulate Subtraction Property Substitution Property

14. If you have any questions: Ask a friend Come in for help Do some extra work (lots of great stuff in the back of the book) Rework some past assignments MOST OF ALL – EVERYONE – Be prepared for the test NEXT TIME.
