1. Happy Tuesday
Go Formative! Graph while you wait for your computer: (-6,2) (2, -6) (-2, -2) x=4 Find the ordered pair where they intersect ( , )? Make sure you have your foldable! If you have colored pens or pencils, bring them!

4. Learning Target Agenda *Reflection Notes 8.G.A.1 *Hands on Practice
*Math Aids Worksheet
8.G.A.1
I can verify congruency by measuring and comparing the properties of rotated, reflected or translated geometric figures.

5. Reflections!

6. Foldable Reflections ~Flip ~Mirrors the image ~Same shape, same size
~Figures are congruent.
~Is reflected over a line (symmetry)

7. Foldable
Write the vertices of A’_________, B’_____________, and C’____________.

8. Hands-On Reflection Practice Working with your team, set up the
original image (YELLOW)
then reflect with it’s
congruent (PURPLE) shape using the
graph sheets and plastic figures.

9. 1. Reflect over y-axis. ?

10. 2. Reflect over x-axis. ?

11. 3. Reflect over line y=x. ?

12. 4. Reflect over y-axis. ?

13. 5. Reflect over x-axis. ?

18. PATTERNS? A(-1, 1) A’ (1,1) B(-1, 5) B’ (1,5) C(-5, 1) C’(5,1)
Let’s examine #1-sketch in comp book and take notes.
A(-1, 1) A’ (1,1) B B’
B(-1, 5) B’ (1,5)
C(-5, 1) C’(5,1) C A A’ C’

19. PATTERNS? A(-1, 1) A’ (-1,-1) B(-1, 5) B’ (-1,-5) C(-5, 1) C’(-5,-1)
Let’s examine #2-sketch in comp book and take notes.
A(-1, 1) A’ (-1,-1) B
B(-1, 5) B’ (-1,-5) C A
C(-5, 1) C’(-5,-1) A’ C’ B’

20. 6. Reflect over line y=x. How can we do this without tools?

21. 6. Reflect over line y=x. Draw the line of reflection.
What do you notice about coordinates for ABCD
And A’B’C’D’ D’ B’ A B C’ A’ C D

22. 6. Reflect over line y=x. A(2, 3) A’ (3,2) B(6, 3) B’ (3,6)D’ B’
A(2, 3) A’ (3,2) A B
B(6, 3) B’ (3,6) C’ A’
C(2, -1) C’(-1,2) C D
D(6, -1) D’ (-1,6)
(x, y)→ (y,x)

23. Draw line of reflection as a dashed line! If you finish early,
