Find the new triangle that undergoes a scale factor of 1.5 and a center of dilation at the origin

b=(4,-2)
a=(2,2)
c=(-4,-4)

1 answer

To find the new triangle after applying a scale factor of 1.5 with a center of dilation at the origin, we need to multiply the coordinates of each vertex of the triangle by the scale factor.

The vertices of the original triangle are:

  • \( A = (2, 2) \)
  • \( B = (4, -2) \)
  • \( C = (-4, -4) \)

We'll apply the scale factor of 1.5 to each vertex:

  1. For vertex \( A \): \[ A' = (1.5 \times 2, 1.5 \times 2) = (3, 3) \]

  2. For vertex \( B \): \[ B' = (1.5 \times 4, 1.5 \times -2) = (6, -3) \]

  3. For vertex \( C \): \[ C' = (1.5 \times -4, 1.5 \times -4) = (-6, -6) \]

Thus, the coordinates of the new triangle after dilation are:

  • \( A' = (3, 3) \)
  • \( B' = (6, -3) \)
  • \( C' = (-6, -6) \)

In summary, the new triangle vertices after the dilation are:

  • \( A' = (3, 3) \)
  • \( B' = (6, -3) \)
  • \( C' = (-6, -6) \)
