Answer: 1/2

Step-by-step explanation: The scale factor of the dilation is 1/2 because it's 1/2 of the other triangle. As you can see it used to be 10, but now it's 5.

Have a good day :D

Answer:

From Triangle ABC to Triangle A'B'C', the scale factor is 1/2

b) 1/2

Step-by-step explanation:

Side Length of Line Segment AC is 8 units

Side Length of Line Segment AB is 6 units

Side Length of Line Segment of BC is 10 units

Side Length of Line Segment A'C' is 4 units

Side Length of Line Segment A'B' is 3 units

Side Length of Line Segment B'C' is 5 units

Checking:

A'C'/AC=4/8=1/2 simplified

Hence, the answer is 1/2 as the scale factor for the dilation.
