Revolt · Accepted Answer

A: EF corresponds to E'F'.; C: ∠EDG ∠E'D'G'; D: ∠DEF ∠D'E'F'; F: The transformation is a rigid transformation.

Question 8

Which type of transformation is shown? The transformation is a transformation. How do the angle measures and side lengths compare? The angle measures of rectangle QRST are the angles measures of rectangle Q'R'S'T'. The side lengths of rectangle QRST are the side lengths of rectangle Q'R'S'T'.

Revolt · Accepted Answer

Selection 1: reflection, a type of rigid; Selection 2: equal to; Selection 3: equal to

Question 9

Which transformation is shown in the figure?

Revolt · Accepted Answer

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

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.
