Hello,

I'm having difficulty with this linear transformation puzzle, I'd be grateful if you could give it a go. I haven't quoted my textbook verbatim, so if there is any confusion please let me know and I'll restate it. Thanks

Referring to the image below, the triangle t is undergoing a number of reflections


A(t) = 1
B(t) = 2
C(t) = 3


BC(t) = 4


(i) Show that operations AB and BA are the same


(ii) Describe the combined operation BC geometrically.


(iii)Simplify C(CB), (CC)B and BC(CB)...using I to denote the identity operation.


(iv) Obtain expressions, as combinations of A, B and C for operations which carry


(a) t to x
(b) t to y
(c) x to t

C(t)=3 means B(3)=4

we also have B(t)=2

A reflection cannot do that
