    |dw:1338667087210:dw| imagine if C was on that firs line... what would the distance be then between C and C'' ?

    is it: Distance between k and m = 2.6 inches Distance from C to the distance from C" to m = 2.6 inches because this is a translation. 2.6 inches + 2.6 inches = 5.2 inches 5.2 inches or not???

    |dw:1338667559696:dw| If maybe that representation makes sense, to see why its 5.2: we have the 2.6 in the center, and then the two segments that compose 2.6 on the outside to make another 2.6.

    if uur doing 3), it says Find the angle of rotation that maps A onto A". so i guess it says to find it in degreess?? right???

    this shows that to get from A to A'' , just double the angle between the two intersecting lines of reflection... :) we didn't give you directly that the angle of rotation is twice that... i thought this clearly shows how much you should rotate to get to where you want to...|dw:1338668814266:dw|
