1. Just for fun… do these (on the back of your warm up) 1.Name 2 pair of alternate interior angles <5 & <3 and <4 & <1 2.What is the sum of m<1 + m<2 + m<3? 180° 3.If m<4 = 65° and m<5 = 50°, what is m<2? 65° 1 3 2 45 4. Find all the angle measures 50° 40° 90° 40° 90° 130° 50°

2. Let’s grade your vocab worksheets ♥Word search/Crossword/Mult Choice

3. Flashcards Pick a partner Get a set of flashcards Work on identifying angles You will have 10 minutes Go

4. Just a little quickie… ♥Please get pg 173 off the front desk and do problems 5-20…. ♥We’re just getting a head start on today’s assignment… ♥We’ll have notes in 15 minutes… ♥Go

5. 3.5 Triangle Sum Theorem & Exterior Angle Theorem

6. Triangle Sum Theorem The sum of the angle measures in a triangle equal 180° 3 2 1 m<1 + m<2 + m<3 = 180°

7. Exterior Angle Theorem (your new best friend) The measure of an exterior angle in a triangle is the sum of the measures of the 2 remote interior angles 3 2 1 4 exterior angle remote interior angles m<4 = m<1 + m<2

8. an example with numbers x 82° 30° y find x & y x = 68° y = 112° 40x10x 2 30xfind all the angle measures 80°, 60°, 40° Do you hear the sirens?????

9. White boards Please get, or have someone get for you; whiteboard marker eraser

10. Finish the assignment On the same paper as 5-20, Please do 21-37 on page 174
