Question

A triangle is dilated by a scale factor of n = One-third. Which statement is true regarding the dilation?

It is a reduction because n > 1.
It is a reduction because 0 < n < 1.
It is an enlargement because n > 1.
It is an enlargement because 0 > n > 1.

Answer 1

It is a reduction because 0 < n < 1.

Since n = 1/3 is between 0 and 1, the dilation makes the triangle smaller (a reduction).
