Question 7

Which transformation is shown in the figure?

Revolt · Accepted Answer

ΔABC was rotated to form ΔA'B'C'. The transformation is isometric.

Question 8

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

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

Question 9

Revolt · Accepted Answer

reflection; rotation; translation

Question 10

What type of transformation maps ΔQRS to ΔQ'R'S'?

Revolt · Accepted Answer

rotation
