Revolt · Accepted Answer

B: [Image: Triangle X Y Z is reflected across line m and then...]

Question 6

What additional information could be used to prove that △ABC ~ △NML? Check all that apply.

Revolt · Accepted Answer

A: ∠B ≅ ∠M; C: △ABC was rotated and dilated by a scale factor between 0 and 1.; E: ∠C ≅ ∠L

Question 7

Determine the similarity transformations that verify △ABC ~ △A''B''C'. The first transformation mapping △ABC to △A'B'C' is a . The second transformation mapping △A'B'C' to △A''B''C' is a .

D: translation left

Question 8

Use the drop-down menus to complete the paragraph proof. We are given that XY is parallel to ZW. If XZ is a transversal that intercepts XY and ZW, angle and angle are alternate interior angles. Since XY is parallel to ZW, we know that these angles are . We also know that angle XVY and angle ZVW are angles, and thus congruent. We can conclude that △XYV ~ △ZWV using the similarity theorem.
