Question

TriangleABC is dilated about the origin.

What scale factor was used to make the image A'B'C?

Answer 1

its gonna be a scale factor of 3

Answer 2

The triangle ABC is dilated by 3 units.

Explanation:

We know that,

Dilation is a transformation that changes the size of the figure by any scale factor.

Now, as we can see that the size of the larger triangle is 3 times the size of the smaller triangle.

Therefore, we can say that the figure ABC is dilated by a scale factor of 3 to form figure A'B'C'.

Hence, the triangle ABC is dilated by 3 units to make A'B'C'.
