Reflection problem 4 If M1(T) and
M2(T) are two reflections of shape T, is it true that
M1.M2(T) = M2.M1(T)? |
Study the above construction. You
should see that the answer is No. Combination of reflections is
non-commutative. Can you move the mirror lines so the two resulting
images coincide? See if you can make this construction yourself:
