Select ALL the sequence of transformations that take kite ABCD to its image kite AEFG. Note: CA=DA and DB=BC.

• Translate kite ABCD by directed line segment AF, then rotate the image 90-degrees clockwise around F.

• Rotate kite ABCD 111-degree clockwise around A. Then reflect it across AE.

• Reflect kite ABCD over point A.

• Rotate kite ABCE 100-degree counterclockwise around A, then reflect it across AF.

ABCD is a square. Trapezoid BCFE is congruent to trapezoid ADFE. G is the midpoint segment of EF. Select ALL the ways we could describe the rigid transformation that takes AEFB to CFED.

• Reflect BCFE across line EF.

• Rotate BCFE 180-degrees counterclockwise around point G.

• Rotate BCFE 180-degrees clockwise around point G.

• Translate BCFE by the directed line segment from F to E, and then reflected across line FE.

• Translate BCFE by the directed line segment from F to E, and then rotate 180-degrees clockwise around point E.
