Question

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

Answer 1

Answer:

$A' = (-4,4)$

$B' = (2,6)$

$C' = (2,0)$

Step-by-step 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:

$A' = A * 2$

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

$A' = (-4,4)$

$B' = B * 2$

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

$B' = (2,6)$

$C' = C * 2$

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

$C' = (2,0)$
