# Ch 55: MTTC Math (Secondary): Triangle Theorems & Proofs

Develop mastery of triangles, theorems and proofs in order to answer relevant questions on the MTTC Math (Secondary) examination. Taking your prior studies into account, the online video lessons in this chapter can be used as part if your a review process.

## MTTC Math (Secondary): Triangle Theorems and Proofs - Chapter Summary

This chapter presents you with information about triangles, theorems and proofs. Add to your knowledge in these areas before you sit for the MTTC Math (Secondary) examination. Re-discover methods for measuring a triangle's sides and for determining whether triangles are congruent. The video lessons include key definitions and practice opportunities. Exploring the concepts in this chapter could help you with:

• Explaining how to use and solve with similar triangles
• Using congruence postulates
• Understanding geometric congruence proofs
• Explaining the converse of a statement
• Providing examples of the AAS, HA and HL theorems
• Using congruence and similarity to prove relationships
• Proving the congruency of right and isosceles triangles
• Describing similarity transformations
• Proving the perpendicular and angle bisector theorems
• Identifying the properties of right triangles

Educated mathematics instructors make an effort to expand your understanding of triangles, theorems and proofs through this chapter's engaging videos. Ask questions and study interactively at your own pace. The lessons include video tags for moving from topic to topic as well as text transcripts. Self-assessment quizzes could determine your readiness for the MTTC Math (Secondary) examination's questions on triangles, theorems and proofs.

### MTTC Math (Secondary): Triangle Theorems and Proofs Objectives

Use your knowledge of triangles, theorems and proofs when you answer questions in the 'Measurement and Geometry' subarea of the four-part MTTC Math (Secondary) examination. This subarea is equal to 22% of the entire examination and score.

You must correctly answer 80 multiple-choice questions as you pursue a mathematics teaching certification in Michigan. There are paper and computer versions of the examination. If you take the paper-based examination, you must finish in under four hours and 30 minutes. The time limit for the computer-administered version is two hours and 30 minutes.
