What is the SAS similarity criterion?

Back

SAS~ stands for Side-Angle-Side similarity, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

What is AAS~ in triangle similarity?

Back

AAS~ stands for Angle-Angle-Side similarity, which states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are similar.

What is the reflexive property in geometry?

Back

The reflexive property states that any geometric figure is congruent to itself, meaning for any segment AB, AB ≅ AB.
