WARM UP ANNOUNCEMENTS -Pick up your assigned calculator -Turn in Unit 5 HW Packet Use the distance formula to find the distance between points A and B on the following coordinate plane. (Hint: page in notes  d = ( 𝑥 2 − 𝑥 1 ) 2 + ( 𝑦 2 − 𝑦 1 ) 2 ) Update your TOC. Glue #1 notes onto pg. 44. (0,5) (4, 0)

#1 Pythagorean Theorem

What is a right triangle? It is a triangle which has an angle that is 90o degrees. The two sides that make up the right angle are called legs. The side opposite the right angle is the hypotenuse.

Yes, it is a right triangle! Example: The measures of the sides of a right triangle are 6, 9, and 𝟒𝟓 . Is this a right triangle? First ask yourself, “What is the longest side?” Take any square roots to get the decimals! Second, list the sides in order from least to greatest. The biggest side is your hypotenuse! Then plug into the Pythagorean Theorem and see if it works! Yes, it is a right triangle! 45 =6.7 6, 45 , 9 62 + 45 2 = 92 36 + 45 = 81

No, it is not a right triangle! Practice Problem: A triangle has sides measuring 39 , 7, and 3. Is this a right triangle? No, it is not a right triangle! (Make sure you work this out on your notes to show Ms. Santos during the brain break!)

BRAIN BREAK

Unit 6 New Celebration Format Instead of having one big Celebration of Knowledge at the end of the unit, we are going to have mini celebrations instead of the warm up each day. You will have the first 5 minutes of class to review the notes from the day before. When the 5 minutes are up, you will have 15 minutes to complete the celebration questions that correspond to the previous day’s lesson. As you are completing the celebration questions, I will pass back the questions from the day before, so you can see what you got. You will need to return them to me when you turn in your current questions. You will get all the questions back on the last day of the unit to do any necessary corrections, if your total grade is less than an 85% (Standard) or 93% (Honors). If you are absent (unexcused) or late to class and missed the Celebration Questions, you will receive a 0 and have to make it up during lunch, after school, or on the last day of the unit.

Homework None! Work on Unit 5 Celebration Corrections!

Exit Ticket Name two methods to determine the distance between two points on a coordinate plane. Which method do you prefer and why?
