7.1-7.4 Unit Review

Front

What does SSS similarity criterion state?

Back

If the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

What does SAS similarity criterion state?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What does AA similarity criterion state?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

How do you determine if two triangles are similar using SSS?

Back

Check if the ratios of the lengths of corresponding sides are equal.

Front

How do you determine if two triangles are similar using SAS?

Back

Check if the ratios of two corresponding sides are equal and the included angles are equal.

Front

How do you determine if two triangles are similar using AA?

Back

Check if two corresponding angles are equal.

Front

What is the formula to find the missing side in similar triangles?

Back

If triangles are similar, then \( \frac{a}{b} = \frac{c}{d} \), where a and b are sides of one triangle and c and d are sides of the other.
