14) find the image of triangle GHJ under the translation of (x,y) (x-1 ,y-8) look at the third picture.

A) triangle ABC
B)triangle NPQ
C)triangle KLM
D)triangle DEF


15) What is the reflection image of P(0, 0) after two reflections, first across x = −3 and then across y = 4?look at the forth picture.
A) (−6, 8)
B)(4, −3)
C)(4, −6)
D)(−8, −6)


16) The figure is reflected across line m and then reflected across line n. What is the resulting transformation?look at the fifth picture

A)reflection
B)rotation
C)translation
D)glide reflection

Answer 1

12. C ends up where A is, at (3, 3).
13. Straight across is 180°.
14. Following one point through this translation leads you to triangle KLM.
15. Since P is 3 units right of x = -3, it will end up 3 units left of it, at -6. As it's 4 units down from y = 4, it will end up 4 units above it, at 8. (-6, 8)
16. It appears to be the same as a translation (it's flipped twice and ends up in the same orientation).
