Warm up What are my new coordinates after this transformation? (4,6) (-2, 5) (2, 1) ( x -2, y + 4) Give an example is coordinate notation for the following: move 6 units down move 4 units left reflection in the y-axis 90°rotation clockwise
Dilations Vocabulary Dilation: is a transformation that changes the SIZE, but not the shape of a figure. Scale Factor: tells how much larger or smaller the image of a dilation is than the preimage. remember this is the starting figure.
Dilation (x,y) (kx, ky) (x,y) (2x, 2y)
Dilation (x,y) (kx, ky) (x,y) (3x, 3y)
Dilation (x,y) (kx, ky) (x,y) (4x, 4y)
