Ch 36: TExES Physics/Math 7-12: Triangle Theorems & Proofs

Watch these lesson videos in preparation for the TExES Physics/Mathematics 7-12 certification exam and review what you know about triangle theorems and proofs.

TExES Physics/Math 7-12: Triangle Theorems & Proofs - Chapter Summary

To prepare you for questions on triangle theorems and proofs which you may see on the TExES Physics/Mathematics 7-12 exam, the professional instructors of this series of lesson videos will lecture over the uses of congruence and similarity, applications of similar triangles and triangle theorems. After this chapter you should be ready to answer question related to:

• Applications of similar triangles
• Triangle congruence postulates and proofs
• Converse of a statement
• Similarity transformations
• Using similarity and congruence to prove relationships in figures
• AAS, HA, HL, LA and LL theorems
• Perpendicular Bisector and Angular Bisector theorems
• Congruency of isosceles triangles

Further improve your knowledge of these topics by completing lesson worksheets and quizzes. Using the quizzes to identify areas of weakness, and improve your understanding of the material you have not mastered using video tags that are linked to key areas of the lesson videos, or lesson transcripts that present the same material but in an alternative written format.

TExES Physics/Math 7-12: Triangle Theorems & Proofs - Chapter Objectives

The TExES Physics/Mathematics 7-12 is a computer based certification exam administered to future educators of related subjects in the state of Texas. Test takers are asked to complete 120 multiple-choice questions in a five hour testing session. Of these question 16% cover material on patterns and algebra and 10% covers geometry and measurements. In these two domains you will see some questions on slopes of similar triangles, measurements of right triangles and uses of similar triangles. Improve your understanding of the theorems and proofs that are used to answer these questions by completing the activities of this chapter.
