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?
To determine the scale factor used to create the copy on the right, we can compare the lengths of corresponding sides. Let's denote the scale factor as x.
In the original triangle (left), the length of the shorter leg is 3 cm, and in the copy (right), the corresponding side has a length of 6 cm. Therefore, we can write the proportion:
3 cm / x = 6 cm
Simplifying this equation, we have:
2 = x
So, Randee used a scale factor of 2 to create the copy on the right from the original on the left.
