What is the definition of similar triangles?

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does the symbol AA~ represent in triangle similarity?

Back

AA~ means 'Angle-Angle Similarity', which states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What does the symbol SAS~ represent in triangle similarity?

Back

SAS~ means 'Side-Angle-Side Similarity', which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

What is the relationship between the sides of similar triangles?

Back

The ratios of the lengths of corresponding sides of similar triangles are equal.

Front

If two triangles are similar, what can be said about their areas?

Back

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

Front

How do you determine if triangles are similar using the AA criterion?

Back

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