So do you know the three types of symmetry and the different types of transitions?

5. Laura<3

Uh i know the symmetry but not transitions

6. brandi2013

Okay so transitions: translation (which is like sliding an image across however many spaces it says to) reflection (acts as a mirror, mirror the image across the X or Y axis) rotation (your rotating an image around a specific point) and..I think I'm missing one still not sure though

7. Laura<3

I know those. I just got confused by the name. lol

8. brandi2013

Okay so I'm going to pick on symmetry first. If you folded the image in half, would the image be the same on both sides? If so it has reflection symmetry. If the image can be rotated around and still look the same as the original, it has rotation symmetry. If you can slide the image and it stays the same, it has translation symmetry

9. brandi2013

So the image has: one line of reflection symmetry (you can only make it the same one way), rotation symmetry, and translation symmetry.

ok cool. (: thanks!

11. brandi2013

and do they tell you what point P is at in the image?

12. Laura<3

No they don't.

13. brandi2013

Well they aren't much fun. Okay let me draw the picture out real quick then

14. brandi2013

The picture would have to been rotated 270 degrees. If it was reflected the new point (P') would have been (-4, -2)

Thanks so much!
