Ch 5: Amsco Geometry Chapter 5: Congruence Based on Triangles

About This Chapter

The Congruence Based on Triangles chapter of this Amsco Geometry Textbook course helps students learn essential geometry lessons of congruence based on triangles. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Congruence Based on Triangles textbook chapter.

How it works:

  • Identify the lessons in the Amsco Geometry Congruence Based on Triangles chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the congruence based on triangles topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn about:

  • Line segments
  • Proving angles and line segments congruent
  • Equilateral and isosceles triangles
  • Working with two pairs of congruent triangles
  • Proving overlapping triangles congruent
  • The angle bisector theorem
  • Basic constructions

Median, Altitude, and Angle Bisectors of a Triangle

1. Median, Altitude, and Angle Bisectors of a Triangle

Line segments in triangles are just clutter; they have special names and qualities depending on how they're drawn. In this lesson, we'll learn about medians, altitudes and angle bisectors.

Congruency of Isosceles Triangles: Proving the Theorem

2. Congruency of Isosceles Triangles: Proving the Theorem

Isosceles triangles have two equal sides. Are the base angles also equal? In this lesson, we'll prove how this is true. We'll also prove the theorem's converse.

Perpendicular Bisector Theorem: Proof and Example

3. Perpendicular Bisector Theorem: Proof and Example

Perpendicular bisectors are multifunctional lines. They're not only perpendicular to the line in question, they also neatly divide it into two equal halves. In this lesson, we'll learn about the perpendicular bisector theorem.

Angle Bisector Theorem: Proof and Example

4. Angle Bisector Theorem: Proof and Example

The angle bisector theorem sounds almost too good to be true. In this lesson, we set out to prove the theorem and then look at a few examples of how it's used.

Geometric Constructions Using Lines and Angles

5. Geometric Constructions Using Lines and Angles

Watch this video lesson to learn about geometric construction and how you can copy line segments and angles without using any numbers. All you need is a straight edge and a compass.

Dividing Line Segments into Equal Parts: Geometric Construction

6. Dividing Line Segments into Equal Parts: Geometric Construction

Watch this video lesson to learn one way to easily divide any line segment into as many equal parts as you need. Also, learn where in real life this skill comes in handy.
