The scale factor or ratio that compares the two diagrams is 0.5.
The scale factor refers to the ratio of an original drawing, model, or dimension to the scale drawing, model, or dimension.
The scale factor may be increasing the original drawing, in which case, we describe it as scaling up.
On the other hand, when the scale factor decreases the original drawing or shape, it is described as scaling down.
The side length of AE in the first diagram = 12 cm
The side length of AE in the second diagram = 6 cm
The scale factor = 6/12 = 0.5
Thus, we can conclude that the second diagram was drawn at a scale factor of 0.5 compared to the first diagram.
Question Completion:
Assume that AE in the first diagram is 12 cm and AE in the second diagram is 6 cm.
