Words can have different meanings, or even shades of meanings. Often the exact meaning depends on the context in which a word is used. In this chapter you’ll use the word similar.When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Are these ratios equal? Triangle ABC is similar to triangle DEF. We can write this using a special symbol, as shown here.Geo HW A Day: Ratio, Proportions, Geometric Mean. We reviewed triangle segments and took a checkpoint.
