### Practice Problems 19 and 20 by D. Kirkland in Math II

In Pearson Success Net section 8.2 Reflections, from the Math I book, the practice problems 19 and 20 give the following challenge. "The work of artist and scientist Leonardo da Vinci (1452-1519) has an unusual characteristic. His handwriting is a mirror image of normal handwriting."

# #19

a. On paper, write the sentence, "Leonardo da Vinci was left-handed."

b. Write the mirror image of the sentence, "Leonardo da Vinci was left-handed."

c. Use Photo Booth to take a picture of both sentences to see if your mirror image sentence is correct. Add the picture to your Tackk.

d. What would Leonardo ask you to practice while writing sentences in a reflection? Use complete sentences in a text box on your Tackk.

e. "Explain why the fact about da Vinci in part (a) might have made mirror writing seem natural to him." Use complete sentences in a text box on your Tackk.

Leonardo would ask me to work on my letter 's' and ask me to write on a straight line. Since I am right-handed, I did not realize that a reflection would be a simple solution to a left-handed situation. I see where it would have been natural to him. If the right hand moves from left to right, then the left hand should move from right to left.

# #20

"Give three examples from every day life of objects or situations that show or use reflections." Take pictures of three objects, graphs or situations in class that show or use reflections. Use complete sentences in text boxes to describe each of the three situations. Add your pictures and your complete sentences to your Tackk.
