# Ch 5: Triangles, Theorems and Proofs: Tutoring Solution

The Triangles, Theorems and Proofs chapter of this High School Geometry Tutoring Solution is a flexible and affordable path to learning about theorems and proofs for triangles. These simple and fun video lessons are each about five minutes long and they teach all of the operations involving triangles, theorems and proofs required in a typical high school geometry course.

## How it works:

• Begin your assignment or other high school geometry work.
• Identify the triangles, theorems and proofs concepts that you're stuck on.
• Find fun videos on the topics you need to understand.
• Press play, watch and learn!
• Complete the quizzes to test your understanding.
• As needed, submit a question to one of our instructors for personalized support.

## Who's it for?

This chapter of our high school geometry tutoring solution will benefit any student who is trying to learn about triangles, theorems and proofs and earn better grades. This resource can help students including those who:

• Struggle with understanding triangle congruence postulates, congruence proofs, similarity transformations or any other triangles, theorems and proofs topic
• Have limited time for studying
• Want a cost effective way to supplement their math learning
• Prefer learning math visually
• Find themselves failing or close to failing their triangles, theorems and proofs unit
• Want to get ahead in high school geometry

## Why it works:

• Engaging Tutors: We make learning about triangles, theorems and proofs simple and fun.
• Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
• Consistent High Quality: Unlike a live algebra tutor, these video lessons are thoroughly reviewed.
• Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about triangles, theorems and proofs on the go!
• Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

## Learning objectives

• Solve problems with similar triangles.
• Use SAS, SSS and ASA triangle congruence postulates.
• Utilize the CPCTC theorem.
• Provide an example of the converse of a statement.
• Explore the use of similarity transformations.
• Prove the relationships of geometric figures, and solve practice problems.
• Provide proof of the AAS, SA and HL theorems.
• Explore the use of the perpendicular bisector theorem and the angle bisector theorem.
• Define the LL and LA theorems.
• Explain the congruency of the base angles of isosceles triangles.
