### Use Proportions to Solve Geometric Problems

6.2

• The Reciprocal Property:

• If two ratios are equal, then their reciprocal is also equal.

• Basically, you can flip ratios to make new equivalent ratios.

If , then

• If you have 2 ratios equal to each other, then the numerators can be turned into a new ratio and the denominators into another new ratio.

• You can add the denominator of each ratio to the numerator to get a new ratio.

XW = 1, XY = 3, YZ = 2, and WV is unknown so WV = x

1(2) = 3x
