Use the image to answer the question. 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)
Since the length of the corresponding sides in the two triangles are 3 cm and 6 cm respectively, the scale factor can be calculated by dividing the length of the copy triangle by the length of the original triangle.
Scale factor = Length of copy triangle / Length of original triangle
Scale factor = 6 cm / 3 cm = 2.
Therefore, Randee uses a scale factor of 2 to create the copy on the right from the original on the left.
