need help wth transformations
want d whole chap summarisd if possible
n ya need help in reflection where the mirror line is slanting

It is summarized here.
unknown:
hey thx a lot
bt ya need fr sheer too
unknown:
the coordinates of the vertices of a square abcd after two transformation are as folllows
a(-2,2) b(2,2) c(2,-2) d(-2,-2)
a'(-2,6) b'(6,2) c'(2,-6) d'(-6,-2)
a"(-6,8) b"(-2,-4) c"(6,-8) d"(2,4)
a) find the matrix which maps abcd onto a'b'c'd'
b) find the matrix which maps a'b'c'd' onto a"b"c"d"
c) find the matrix which maps abcd onto a"b"c"d"
d) find the matrix which maps a"b"c"d" onto abcd (this shalll be d inverse of d ans c rite)
plzz give a detailed explanation of hw to get to d ans
the need is urgent
thx fr d help :D
