Atriangle has verticies a(-2, 3), b(0,0), and c (1,1).
find the coordiates of the triangle if it is reflected over the x-axis, then dilated by a scale factor of 3.
after that find the coordinates if the original triangle is dilated by a scale factor of 3, then reflected over the x-axis.

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.
