Answer:
The triangle P has been enlarged by a scale factor of 3 about the centre of enlargement (1, 0)
Step-by-step explanation:
When you are looking an enlargement you need to calculate:
- the scale factor
- the centre of enlargement
The length of sides of shape Q are 3 times the length of sides of shape P, so the shape is enlarged by a scale factor of 3.
To calculate the centre of enlargement, draw 3 lines connecting each of the corresponding points and find where the 3 lines converge. (see attached sketch)
So the centre of enlargement is (1, 0)
