Exercise 8 Page 459

AB/DB = BC/BF

Practice makes perfect

We are given the following triangles and we are told that they are similar.

We are asked to complete the following statement.

AB/DB = BC/â–  To do so, let's recall the Side-Angle-Side Similarity Theorem.

Side - Side - Side Similarity

If the corresponding sides of two triangles are proportional, then the triangles are similar.

Looking at our triangles, we can see that the ratio ABDB is proportiional to BCBF. Therefore, we can complete the statement. AB/DB = BC/BF
