Question

∆A′B′C′ is a dilation image of ∆ABC. Which is the correct description of the dilation?




center A and scale factor 4


center A and scale factor 5


center C and scale factor 5


center C and scale factor 4

Answer 1

Answer:

Option B)

centre A and scale factor 5

Step-by-step explanation:

Given in the question that,

∆A′B′C′ is a dilation image of ∆ABC means  ∆ABC is enlarged.

side AC of ∆ABC = 2

side A'C' of ∆A'B'C' = 10

Formula to use:

factor of dilation = A'C' / AC

                             = 10/2

                             = 5

To find the centre of dilation, connect all points with the corresponding points and see where the meets.
