What is Triangle Similarity?

Back

Triangle similarity refers to the relationship between two triangles that have the same shape but may differ in size. This means their corresponding angles are equal and their corresponding sides are in proportion.

What does AA Similarity stand for?

Back

AA Similarity stands for Angle-Angle Similarity. If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

What does SSS Similarity stand for?

Back

SSS Similarity stands for Side-Side-Side Similarity. If the three sides of one triangle are proportional to the three sides of another triangle, the triangles are similar.

What does SAS Similarity stand for?

Back

SAS Similarity stands for Side-Angle-Side Similarity. If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

If ∆ABC≅∆XYZ, what can be concluded about their corresponding sides?

Back

If ∆ABC≅∆XYZ, then the corresponding sides are equal in length: AB=XY, BC=YZ, AC=XZ.

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

Back

No, two triangles cannot be similar if only one pair of angles is equal; at least two pairs of angles must be equal.

What is the relationship between the sides of similar triangles?

Back

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