Triangle ABE is similar to triangle DCE. If you were writing a proof to show this to be true, one of the statements would be $$\angle\ AEB\ \cong\ \angle\ DEC$$ . What reason would you give for this statement?

If parallel lines are cut by a transversal, then alternate interior angles are congruent

Which series of transformations could be used to show ΔDCE is similar to ΔABE?

Rotation $$180\degree$$ about point E and a dilation of $$\frac{1}{2}$$ from point E

Reflection over BC and a dilation of 1 / 2 from point E

Reflection over AD and a dilation of 1 / 2 from point E

Rotation 90 o about point E and a dilation of 1 / 2 from point E

Which of the statements is true about the graphed triangles?

They are similar, because the image can be obtained by dilating from the origin with a scale factor of 1/2.

They are similar, because the image can be obtained by dilating from the origin with a scale factor of 2.

They are not similar, because the sides are not proportional.

They are not similar, because the sides are proportional.

Which similarity theorem, if any, proves that these triangles are similar?

None, the triangles are not similar

To prove $$\Delta\ ZGP\ \sim\ \Delta\ BGR$$ , one of the statements would be $$\angle\ ZGP\ \cong\ \angle\ BGR$$ . Which of the following would be the reason for this statement?

If parallel lines are cut by a transversal, then alternate interior angles are congruent.

Which similarity theorem, if any, proves that these triangles are similar?

None, the triangles are not similar
