Determine the relationship between the triangles.

• SSS∼

• SAS∼

• AA∼

• Not similar

If two polygons are similar, then the corresponding side lengths are ___________.

• congruent

• similar

• equal

• proportional

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they are the same shape and side lengths are proportional.

• No, not similar because they are the same shape, but side lengths are not proportional.

• Yes, same shape

• No, different sizes
