4/12 CW 8.3 Triangle similarity SSS SAS AA

Front

What does AA Similarity mean in triangle similarity?

Back

AA Similarity means that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Front

What does SSS Similarity mean in triangle similarity?

Back

SSS Similarity means that 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 mean in triangle similarity?

Back

SAS Similarity means that if two sides of one triangle are proportional to two sides of another triangle and the included angle is congruent, then the triangles are similar.

Front

Are all angles in similar triangles congruent?

Back

True, all corresponding angles in similar triangles are congruent.

Front

If ∆ABC≅∆XYZ, what can we say about the sides AB and XY?

Back

AB≅XY, meaning the lengths of sides AB and XY are equal.

Front

What is the relationship between the sides of similar triangles?

Back

The corresponding sides of similar triangles are in proportion.

Front

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

Back

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

Front

What is the significance of the included angle in SAS Similarity?

Back

The included angle must be congruent for SAS Similarity to hold true.

Front

Can two triangles be similar if only one pair of angles is congruent?

Back

No, at least two pairs of angles must be congruent for the triangles to be similar.

Front

What is the formula for checking SSS Similarity?

Back

If a/b = c/d = e/f, where a, b, c, d, e, and f are the lengths of the sides of the triangles, then the triangles are similar.
