Question 1
Which pair of figures shows a dilation with a scale factor
of 1 1/2 centered at the origin?
-Figures GHI and JKL
-Figures ABC and DEF
-Figures MNP and VMW
-Figures QRS and TRU

QRS and TRU

Step-by-step explanation:

A dilation of 1 + 1/2 means that the second image is (1 + 1/2) times the length of the first one.

for this, you can check with one of the sides of the triangles:

with the triangles QRS and TRU we have that the line RS has a length of 2 units, then the length of the RU must be 1 and 1/2 times that length:

RU = (1 + 1/2)*2 = 2 + 1 = 3 units

and we can see in the graph that the segment RU has a length of 3 units, so this is a dilation with a scale factor of 1 + 1/2

For the other 3 options we can see that in the top left one bot triangles are equal, and in the bottom two the dilation is with a scale factor of 2.
