B: reflection, a type of rigid

Question 10

All side lengths of ΔJKL equal 2 units. A transformation maps ΔJKL to ΔJ'K'L'. The length of side J'K' is 5 units. Is this a rigid transformation?

Revolt · Accepted Answer

B: No, at least one segment length is not preserved, making this a nonrigid transformation.
