Unit 4 Lesson 4 Using Corresponding Parts of Congruent Triangles
Unit 4 Lesson 4: Using Corresponding Parts of Congruent Triangles
Lesson Overview
Corresponding Parts
What You Will Learn
- exploring how triangles that are proven to be congruent will have corresponding part pairs that are also assumed to be congruent
Column 1
With SSS, SAS, ASA, and AAS, you can use three congruent parts of two triangles to show that the triangles are congruent. Once you know that two triangles are congruent, you can make conclusions about their other corresponding parts because, by definition, corresponding parts of congruent triangles are congruent.
Essential Understanding
If you know two triangles are congruent, then you know that every pair of their corresponding parts is also congruent.
