Question

14. Describe the image of D first reflected across line I, then across line m.

15. Is one flag a translation image of the other, or a rotation image? Explain.

19. The dashed triangle is a dilation image of the solid triangle with the center at the origin. Is the dilation an enlargement or a reduction? Find the scale factor of the dilation.

@ASNinja please Help!

Answer 5

sorry, didn't see this until now

Answer 6

14. 180 degree rotation; it's the same
15. It's a translation, it just shifted down not rotated
19. reduction, scale factor: 0.5

Answer 7

well, there is no work to show for 14, you could draw lines to show the transformations. for 15, draw a line to show the translation
for 19, the triangle is getting smaller, and the scale factor is just -2/-6 = 1/3
oops... the original scale factor that I put for #19 is incorrect. it should be 1/3
