1 1/3

1 2/2

1/2

Answer 1

To determine the scale factor, we need to compare the corresponding side lengths of the two triangles.

In the original triangle, the length of the base is 15 inches, and in the copy on the right, the length of the base is 30 inches.

The scale factor is calculated by dividing the length of the corresponding side in the copy (30 inches) by the length of the corresponding side in the original (15 inches).

30 inches ÷ 15 inches = 2.

Therefore, Randee uses a scale factor of 2 to create the copy of the triangle on the right from the original on the left.
