Question

The coordinates of triangle ABC are A(−4, 3), B(2, 3), and C(4, −1). A line segment runs through the triangle with endpoints Y(0, 1) and Z(3, 1). If triangle ABC is dilated by a scale factor of 2 creating the new triangle of A′B′C′, what can you say about the length of line segment Y′Z′?

Answer 1

We can say that the length of line segment Y'Z' will increase by a scale factor of 2.
