Write a paragraph proof of the Corollary to Theorem 3-4.

Corollary to Theorem 3-4 if u dk:

Any rigid motion can be expressed as a composition of reflections.

If... M is a rigid motion

Then... \(M=r_ℓ or M=R_ℓ \cdot R_m or M= R_ℓ\cdot R_m \cdot R_n\)

Note that the black dot is not multiplication, but it is the symbol to represent a composition of rigid motions.

And, in your proof, can you only use knowledge that a geometry student learns in the first half of his school year? (that's me)
