What does AA∼ mean in the context of similar triangles?

Back

AA∼ means that two triangles are similar if they have two corresponding angles that are equal.

Front

What does SAS∼ signify in triangle similarity?

Back

SAS∼ indicates that two triangles are similar if two sides are in proportion and the included angle is equal.

Front

What is the significance of AAA∼ in triangle similarity?

Back

AAA∼ means that if two triangles have all three corresponding angles equal, they are similar, but it is not a valid criterion for proving similarity.

Front

What does SSS∼ represent in triangle similarity?

Back

SSS∼ means that two triangles are similar if all three corresponding sides are in proportion.

Front

What is the relationship between angles in similar triangles?

Back

In similar triangles, corresponding angles are equal.

Front

What is the relationship between sides in similar triangles?

Back

In similar triangles, the lengths of corresponding sides are in proportion.

Front

If two triangles have one angle equal and the sides including that angle are in proportion, what can be concluded?

Back

The triangles are similar (SAS∼).

Front

If two triangles have two angles equal, what can be concluded?

Back

The triangles are similar (AA∼).

Front

What does it mean if two triangles are 'not similar'?

Back

It means that the triangles do not have the same shape, and their corresponding angles and sides do not satisfy the criteria for similarity.

Front

What is the importance of the included angle in SAS∼?

Back

The included angle must be equal for the triangles to be considered similar under the SAS criterion.
