1. Which transformations of the plane are distance-preserving
transformations?

Step-by-step explanation: The transformations in Module 1—translations, reflections, and rotations—are all transformations of the plane that are rigid motions, or they are distance-preserving.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
