Answer:
Rectangle J
Step-by-step explanation:
The ratio of the length to the width of triangle ABCD is 8:2, but this is equivalent to 4:1 by dividing by 2 (like how 1/4 is equal to 2/8). You can use this ratio for the rest of the rectangles:
F: 12:3 (divide by 3 for each)= 4:1
G: 2:0.5 (divide by 0.5)= 4:1
H: 10:2.5 (divide by 2.5)= 4:1
J: 10:4 (divide by 4)= 2.5:1
J is the odd one out, therefore it is not similar to ABCD.
