Question
How do you determine the scale factor of a trianlge?
Expert Solution
Step 1
Similar triangles are objects that have the same shape and angle size, but their side lengths are different. The corresponding sides of the triangles, however, are in the same length ratio, also called the scale factor. Multiplying the smaller triangle's side lengths by the scale factor will give you the side lengths of the larger triangle. Similarly, dividing the larger triangle's side lengths by the scale factor will give you the side lengths of the smaller triangle.
