Use the figure to answer the following question.

Which of the following statements is False about the figure? Select all that apply.

• d + b = 180

• c + b = d + c

• Reflect across line CE. Then, angle CBD is the image of angle EBA.

• Rotate 180 degrees using center B. Then, angle CBD is the image of angle EBA.

• Reflect across the angle bisector of angle ABC. Then, angle CBD is the image of angle ABE.

Carla wants to prove that the measures of the 3 angles in a triangle always have a sum of 180°. She decided to prove this conjecture using rigid motion. She began with triangle ABC shown in Figure 1.

Which statement best describes the rigid motion she used in Figure 2 to support her proof?

• Reflect triangle ABC across AB and across AC.

• Translate triangle ABC along directed line segment AD and along directed line segment AE.

• Rotate triangle ABC 180° about the midpoint of AB and about the midpoint of AC.

• Reflect triangle ABC across AB and then translate the image along directed line segment DE.
