Homework Statement
Prove or disprove: Every translation is a product of two non-involutory rotations.
Homework Equations
The Attempt at a Solution
:[/B]I am not sure if I got the right proof for the special situation: A translation is the product of two reflections with parallel reflections lines. And the reflections lines can be written as the product of two non-involutory rotations of 90 degrees, which means that the translation is a product of two non-involutory rotations under this specific condition.
I don't know how to deal with the general conclusion. What happens when the two rotations have different centers? How should I prove the statement for a general case?
