Answer:
* The scale factor of the dilation is 2.5
Step-by-step explanation:
* Lets talk about dilation
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the
figure does not change.
- The scale factor, measures how much larger or smaller
the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
* In the problem
- The vertices of the triangle is A (0 , 0) , B (0 , 4) , C (6 , 0)
and its image A' is (0 , 0) , (0 , 10) , (15 , 0)
∵ 10 ÷ 4 = 2.5
∵ 15 ÷ 6 = 2.5
∴ The scale factor is 2.5
∵ 2.5 > 1
∴ The image of the triangle will be larger
* The scale factor is 2.5
