Explanation:
Similar figures have different side lengths but corresponding angles are congruent.
The figure you sketch will have side length:
- s = 12k, where k is the scale factor
When k > 1, you sketch a larger figure, when 0 < k < 1, you sketch a smaller figure than pictured.
See attached, the two figures, one has side of 18 when k = 1.5, another one has side of 6, when k = 0.5
