What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the ratios of their corresponding sides are proportional.

What is the Angle-Angle (AA) similarity criterion?

Back

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

What does it mean for triangles to be similar by side-side-side (SSS) similarity?

Back

If the ratios of the lengths of corresponding sides of two triangles are equal, then the triangles are similar.

What is the Side-Angle-Side (SAS) similarity criterion?

Back

If one angle of a triangle is equal to one angle of another triangle and the lengths of the sides including these angles are in proportion, the triangles are similar.

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

Back

Yes, because the ratios of the corresponding sides (3:6, 4:8, 5:10) are all equal.

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

Back

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

What is the significance of the term 'corresponding' in similar triangles?

Back

'Corresponding' refers to angles or sides that are in the same relative position in different triangles.
