1. A reflection maps A to B and B to C. Given AB=12, find AC.

 

2. A dilation with scale factor -3 maps X to X' and Y to Y'. Given X'Y'=2, find XY.

 

3. As shown in the diagram, angle MOL = 30 degrees and A is a point inside angle MOL with OA=6. Let B and C be points on rays OM and OL respectively. Find the smallest possible perimeter of triangle ABC.

I got the first one! Basically it was super simple but the wording made it confusing. BC and AB had to be reflected on one reflection "line" therefore C is in the same position as A making the answer 0!
