Reflections 1 State the coordinates of C’:
Reflections 1 ANSWER C’ = (-2, 0)
Reflections 2 Name the line of reflection:
Reflections 2 ANSWER x axis
Reflections 3 Name the line of reflection:
Reflections 3 ANSWER x = -2
Reflections 4 First reflect over x = -2, then over x = 1. A. What single transformation would have been the same as these two reflections?
Reflections 4 ANSWER 2 times 3 (distance between parallel lines) = 6, So a translation of right 6.
Rotations 1 Emily is planting pumpkins, using a coordinate grid as a guide. She plants a pumpkin at (-3, 2) but then decides to rotate it 180°. Where is the pumpkin now?
Rotations 1 ANSWER (3, -2)
Rotations 2 Describe the rotation:
Rotations 2 ANSWER 90° counterclockwise about (0, 0)
Rotations 3 A is plotted at (5, 4) and is then rotated 90° counterclockwise about the origin and then slid 2 to the right. What are the coordinates of A’’?
Rotations 3 ANSWER A’’ (-2, 5) A is plotted at (5, 4) and is then rotated 90° counterclockwise about the origin and then slid 2 to the right. What are the coordinates of A’’?
Rotations 4 Marcella planted some tomatoes at (2, -4). They were not getting enough sun so Riley advised her to slide them 3 left and then rotate them 90° clockwise about the origin. Where are Marcella’s tomatoes?
Rotations 4 ANSWER Marcella planted some tomatoes at (2, -4). They were not getting enough sun so Riley advised her to slide them 3 left and then rotate them 90° clockwise about the origin. Where are Marcella’s tomatoes? (-4, 1)
