Unit 9: Transformation Geometry

Translations: if you have the coordinates (4,5) in quadrant I and you had to translate it (x-6,y-7) what would the new coordinates and quadrant would be? ((4)-6,(5)-7) = (-2,-2) the coordinates would be (-2,-2) and the quadrant would be IV.

the quadrants are positioned like this: top left: II top right: I bottom left:III bottom right: IV

My three tips to transformation success 1. In reflections remember to flip the correct value by flipping the oppostite value of the axis your flipping over ie: if flipping over the x-axis change the y-value to its opposite. 2. Use a second piece of graph paper when rotating. It makes rotations much easier to visualize. 3. In Translations whatever you do to one ordered pair do to to the others ie: don't add 5 and 6 to one pair and subtract 4 and 1 from another. 4. Ok so I don't know if anyone else had this problem, but I did make sure you always multiply when doin dialations! I would always add and my figure would always be smaller then everyone elses. So make sure that you multiply instead of adding! I couldn't find a figure of a translation but I found a graph on [|www.__purplemath.com__]. Another good website is [|www.Mathisfun.com].
