# Ch 35: GACE Math: Triangles, Theorems & Proofs

As you prepare for the GACE Mathematics exam, review the material of this chapter to reinforce what you know about proving the triangles. With focused study, you'll fortify your understanding of the parts, properties, and theorems used to solve problems with triangles.

## GACE Math: Triangles, Theorems & Proofs - Chapter Summary

Use this chapter to improve your ability to work geometrical problems involving triangles as part of your preparation for the Georgia Assessments for the Certification of Educators (GACE) in Mathematics. In these lesson videos, our professional instructors will guide you through a series of examples and problems with triangles, demonstrating the use of theorems and proofs. Our instructors will help you prepare for test items on:

• Triangle congruence postulates and congruence proofs
• Finding and assessing the converse of a statement
• Angle-Angle-Side, Hypotenuse Angle, and the Hypotenuse Leg Theorem
• Perpendicular bisector theorem and angle bisector theorem
• Right triangles and the LA and LL theorems
• Congruency of isosceles triangles

Take a look at each of the videos in the order that you prefer. The chapter is completely self-paced, so you can re-watch the lessons until you fully understand their concepts. You may take the follow-up quizzes to test your retention.

### GACE Math: Triangles, Theorems & Proofs Objectives

GACE Mathematics is used in the state of Georgia to measure educators' mathematical abilities. This computer-based certification exam is made up of two subtests that can be taken together or at separate times. There are 45 multiple-choice questions on each of the the GACE Mathematics Tests, and they both have a two-hour time limit. The Geometry subarea of Test II contains about 30% of the subtest's questions, and some may focus on triangles, theorems and proofs. This chapter has been compiled to help you improve your knowledge of these areas so that you will be prepared for them on test day.
