Front

What does AA Similarity mean in triangles?

Back

AA Similarity (Angle-Angle Similarity) states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SSS Similarity mean in triangles?

Back

SSS Similarity (Side-Side-Side Similarity) states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What does SAS Similarity mean in triangles?

Back

SAS Similarity (Side-Angle-Side Similarity) states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

How can you determine if two triangles are similar?

Back

You can determine if two triangles are similar by checking for AA, SSS, or SAS similarity.

Front

If triangle ABC is similar to triangle DEF, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

If triangle ABC has sides of lengths 3, 4, and 5, and triangle DEF has sides of lengths 6, 8, and 10, are they similar?

Back

Yes, they are similar by SSS Similarity because the sides are in proportion (3:6, 4:8, 5:10).

Front

If two triangles have one angle of 60 degrees and the other angles are 30 degrees and 90 degrees, are they similar?

Back

Yes, they are similar by AA Similarity because they have two angles equal.

Front

What is the value of x if triangle ABC is similar to triangle DEF and the sides are in the ratio 2:3?

Back

If the sides are in the ratio 2:3, then x can be found using the proportion of the sides.

Front

If triangle ABC has a side of length 10 and triangle DEF has a corresponding side of length 15, what is the scale factor?

Back

The scale factor is 10:15 or 2:3.

Front

What is the relationship between the areas of two similar triangles?

Back

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