Question

If triangle ABC is dilated using a scale factor of 2, what will be the coordinates of A after the transformation

Answer 1

`A' = (-4,4)`

Explanation:

Given

`A = (-2,2)`
`B = (1,3)`
`C = (1,0)`

`k =2` --- scale factor

Required

Determine A'

This is calculated as:

`A' = A * k`

`A' = (-2,2) * 2`

`A' = (-2 * 2,2 * 2)`

`A' = (-4,4)`
