What is Triangle Similarity?

Back

Triangle similarity refers to the property of two triangles having the same shape but not necessarily the same size. This means that 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'. It states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

What does SSS Similarity stand for?

Back

SSS Similarity stands for 'Side-Side-Side Similarity'. It states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

What does SAS Similarity stand for?

Back

SAS Similarity stands for 'Side-Angle-Side Similarity'. It states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

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

Back

The included angle in SAS Similarity is crucial because it must be equal for the triangles to be considered similar, along with the proportional sides.

Can two triangles be similar if they have no equal angles?

Back

No, two triangles cannot be similar if they have no equal angles. Similar triangles must have at least two equal angles.
