Right Triangle Congruence Isosceles and equilateral triangles aren't the only classifications of triangles with special characteristics. Right triangles are also significant in the study of geometry and, as we will see, we will be able to prove the congruence of right triangles in an efficient way. Before we begin learning this, however, it is important to break down right triangles... read more

Congruent Triangles A very important topic in the study of geometry is congruence. Thus far, we have only learned about congruent angles, but in this section we will learn about the criteria necessary for triangles to be congruent. Learning about congruence on this level will open the door to different triangle congruence theorems that characterize geometry. Corresponding Parts Recall... read more

Triangle Congruence - SSS and SAS We have learned that triangles are congruent if their corresponding sides and angles are congruent. However, there are excessive requirements that need to be met in order for this claim to hold. In this section, we will learn two postulates that prove triangles congruent with less information required. These postulates are useful because they only require... read more

Triangle Congruence - ASA and AAS We've just studied two postulates that will help us prove congruence between triangles. However, these postulates were quite reliant on the use of congruent sides. In this section, we will get introduced to two postulates that involve the angles of triangles much more than the SSS Postulate and the SAS Postulate did. Understanding these four postulates... read more
