Question

Move the horizontal and vertical sliders to stretch the image of the triangle. When you've settled on a pair of transformed images, record the coordinates of the images in the table. Be sure to list coordinates in both the horizontal (x) and vertical (y) directions. Also record the scale factors, nx and ny. Do this at least three times to fill the table.

Answer 1

nx A A′ B B′ C C′

0.5 (2, 1) (1,1) (4, 2) (2,2) (5, 1) (2.5,1)

1 (2, 1) (2,1) (4, 2) ( 4,2) (5, 1) (5,1)

1.5 (2, 1) (3,1) (4, 2) (6,2) (5, 1) (7.5,1)

ny A A′ B B′ C C′

0.5 (2, 1) (2,0.5) (4, 2) (4,1) (5, 1) (5,0.5)

1 (2, 1) (2,1) (4, 2) (4,2) (5, 1) ( 5,1)

1.5 (2, 1) (2,1.5) (4, 2) (4,3) (5, 1) (5,1.5)
