Question

Identify the coordinates of triangle ABC when it is dilated by a scale factor of 2 from the origin (0,0).

Answer 1

`A' = (-4,4)`

`B' = (2,6)`

`C' = (2,0)`

Explanation:

Given [Missing from the question]

`A = (-2,2)`

`B= (1,3)`

`C= (1,0)`

`k = 2` --- scale factor

Required

The new coordinates

The new coordinate is calculated by:

`New = Old * k`

So, we have:

`A' = A * 2`

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

`A' = (-4,4)`

`B' = B * 2`

`B' = (1,3) * 2`

`B' = (2,6)`

`C' = C * 2`

`C' = (1,0) * 2`

`C' = (2,0)`
