Randee draws these two triangles with lengths given in centimeters. What scale factor does she use to create the copy on the right from the original on the left? (1 point)
A. 1 2/3
B. 2
C. 1 1/3
D. 1/2
To find the scale factor, we can compare the corresponding side lengths of the two triangles. The vertical side of the original triangle on the left is 6 cm, and the corresponding side on the copy triangle on the right is 4 cm. Therefore, the scale factor is 4/6, which simplifies to 2/3.
Therefore, the answer is A. 1 2/3.
