chandelier hangs in the center of the ceiling. The graphic Minh painted on the ceiling is a pentagon. Assuming that the chandelier is located at , the pentagon’s coordinates are A (-8,1) B (-9,3) C (-6,2) D (-3,5) E (-4,1
Minh wants to have the same graphic design duplicated in another location on the ceiling. She is considering four ideas.
(a) reflecting pentagon over the y-axis
a. Graph new pentagon when pentagon is reflected over the y-axis. What are the coordinates of pentagon ?
b. Write a math rule or explanation using words that describe a reflection of over the y-axis.
c. Using this rule, where would be located if reflected over the y-axis?
(b) rotating pentagon 90° clockwise about the origin
a. Graph the new pentagon when pentagon is rotated 90° clockwise about the origin. What
