Sketch the two similar triangles at right on your own paper. Find the scale factor and the missing side lengths. Homework Help ✎
Since the scale factor applies to all sides of the shape equally, the two triangles share a common side ratio.
Based on the triangles above, use the given side lengths to find the scale factor ratio between the two triangles.
While each triangle is missing a certain side length, do you notice a pair of sides that are both apparent?
Use the scale factor you have solved for to determine the missing side lengths by either multiplying or dividing.
