Question

I’ve tried everything I watched videos but nothing is working pls some 1 help me

Answer 1

This is a dilation with a scale factor of 2 since the sides of Q are enlarged and tripled the sides of the initial triangle P.

Answer 2

The triangle P has been enlarged by a scale factor of 3 about the centre of enlargement (1, 0)

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)
