Hey guys,  so I really need to get these right. I am not that good with graphs so if you could help, that'd be great! The graphs are located at the bottom of the question, for both questions.

 

1.What is the sequence on transformations that maps triangle ABC  to triangle A'B'C'?

Select from the drop down menus to correctly identify each step.

 

Step 1 options- 

reflect across y=3

reflect across the x axis

reflect across the y axis

reflect across y=1

 

Step 2 options-

rotate clockwise 45 degrees around the origin

rotate counterclockwise 45 degrees around the origin

rotate clockwise 180 degrees around the origin 

rotate counterclockwise 90 degrees around the origin

 

2. Which statements can explain why triangle ABC is congruent to triangle EDC?

Select each correct answer.

 

-triangle EDC is triangle ABC rotated clockwise 180dg about point C

-triangle ABC is triangle EDC rotated 90dg

-triangle EDC is triangle ABC translated 4 units to the left  and reflected across the y axis

-Triangle ABC is triangle EDC reflected across the y axis and reflected across the x axis

(1) reflect across y=3

     rotate counterclockwise 90 degrees around the origin
