Identifying Congruent Triangles
This final page focuses on identifying when to use the SSS or SAS postulates to prove triangle congruence. It presents several scenarios and asks students to determine which postulate, if any, can be used to prove congruence.
Example: One problem shows two triangles with three pairs of congruent sides marked. The solution explains that SSS can be used to prove these triangles congruent.
Example: Another problem presents two triangles with two congruent sides and one congruent angle marked. The solution points out that SAS cannot be used because the given angle is not included between the congruent sides.
These examples help students distinguish between situations where SSS, SAS, or neither postulate can be applied.
Highlight: It's important to carefully examine the given information and the position of congruent parts when deciding which postulate to use.
The page concludes with a "Got It!" section, reinforcing the concepts learned throughout the lesson.
Vocabulary: Reflexive property is often used in these proofs, stating that a side is congruent to itself.
This comprehensive review of SSS and SAS postulates provides students with the tools to prove triangle congruence in various scenarios, enhancing their understanding of geometric proofs.
