7. MGSE8.G.3: Square ABCD is located on a coordinate plane. The coordinates for three of the vertices are listed below A. 2,7 C (8.1) D 2,1 Square ABCD is dilated by a scale factor of 2 with a certer of dilation at the orgin, to form square A'B'C'D'. Part A: Determine the coordinate of vertex B. Explain how you determined your answer. Part B: What are the coordinates of the four vertices for square A'B'C'D? Explain how you determined Your answer

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
