<h2>Answer </h2>
You should check the following:
The length of AB is 2
The length of A'B' is 3
The scale factor is
- To find the length of AB, we will use the distance formula:
From the picture we can infer that and
, so let's replace the values.
The length of AB is 2, so you should check the first answer
- To find the length of A'B', we will use the distance formula one more time:
From the picture we can infer that and
, so let's replace the values.
Since the length of A'B' is 3, you should also check the second answer as well.
- In a transformation (in this case a dilation) the pre-image is the original shape and the image is the shape after the transformation.
Since the image is bigger than the pre-image, the third answer is false.
- Let be the scale factor
We know that the length of AB is 2 and we need to multiply that length by the scale factor to get length of A'B' i.e 3, so:
Since the scale factor is , you should check the fourth answer as well.
- We already prove that the scale factor is , so the fifth answer is false.
