Expert Solution

Step 1

If a triangle is dilated by a scale factor k with the center of dilation at the origin, i.e., (0,0), then the dilation is given by

$(x, y) \to (k x, k y)$

$\frac{Perimeter of the dialated figure}{Perimeter of the original figure} = \frac{side of the dialated figure}{Corresponding side of the original figure} = k$ ...(i)

The dilated figure is similar to the original figure.

We know that the corresponding angles of similar figures are congruent.

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
