Triangle Similarity: AA Answers

Triangle A B C is reflected and then dilated to form smaller triangle A double-prime B double-prime C double-prime

Multiple similarity transformations are performed on a triangle. Which elements must be preserved?

Triangle A E C is shown. Line segment B D is drawn near point C to form triangle B D C.

On a coordinate plane, triangle A B C has points (negative 9, 3), (negative 9, 6), (0, 3) and triangle A double-prime B double-prime C double-prime has points (3, negative 1), (3, negative 2), and (0, negative 1).

Two similar triangles are shown.

Which composition of transformations will create a pair of similar, not congruent triangles?

Read the proof.Given: AB ∥ DEProve: △ABC ~ △EDC

The composition is applied to △RST to create the image of △R"S"T", which is not shown.

Right triangle ABC is reflected over AC, then dilated by a scale factor of to form triangle DEC. Which statements about the two triangles must be true? Select three options.

Triangle A B C is reflected across side A C and then is dilated to form smaller triangle D C E. Angles B C A and D C E are right angles.
