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)
