§7-1 Using Proportions I remembered this property as “Going Fishing”:

Example 1. Solve the proportion.

Only one minor issue comes up… Sometimes you get what are called extraneous solutions. These are solutions that don’t actually work. Example 2. Solve the proportion: Now check each solution in the original proportion…

When does this happen? When a denominator simplifies to 0… Try it out… Example 3. Solve the proportion:

Corresponding Sides are Proportional

Example. Corresponding sides of polygon ABCDE are proportional to the sides of polygon FGHIJ. Find FG. 18 cm 15 cm 17 cm 15 cm 12 cm 4 cm 6cm
