Question

In the similaritytransformation of AABCto AFED, AABC was dilated bya scale factor of [? 1, reflectedacross the [ 1, and movedthrough the translation [1E

Answer 1

Given

Triangle ABD and DEF

Find

Scale factor

Step-by-step explanation

in triangle ABC , the length of AC is 6 units.

let x be the scale factor

this side is transformed into side DF

the lendth of DF is 3 units.

since AC is transformed into DF

so ,

6x = 3

x = 1/2

A(-8 , 2) and D (2 , 0)

Final Answer

Hence , the scale factor is 1/2 , dilated across the y - axis

so , the correct option is B ,
