Question 3

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

Revolt · Accepted Answer

A: ∠BDC and ∠AED are right angles

Question 4

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

Revolt · Accepted Answer

A: (negative three-halves, nine-halves)

Question 5

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

Revolt · Accepted Answer

D: a rotation, then a dilation

Question 6

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.

Revolt · Accepted Answer

D: The triangles are similar because all pairs of corresponding angles are congruent.
