Ch 7: Glencoe Math Connects Chapter 7: Two- and Three-Dimensional Geometry

About This Chapter

The Two- and Three-Dimensional Geometry chapter of this Glencoe Math Connects Companion Course helps students learn the essential lessons associated with two- and three-dimensional shapes. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Two- and Three-Dimensional Geometry textbook chapter.

How It Works:

  • Identify the lessons in the Glencoe Two- and Three-Dimensional Geometry chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the two- and three-dimensional geometry 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:

  • How to use a protractor to draw and measure angles
  • The types of angle pairs
  • The differences between transverse, parallel and perpendicular lines
  • The types of angles
  • Triangle properties
  • How to group triangles by sides and angles
  • How to solve angle and triangle math problems
  • Properties of shapes
  • The definition of polygons
  • The parts of regular polygons
  • Examples of 3D shapes
  • The properties of 3D objects
  • The meaning and examples of polyhedrons

Parallel, Perpendicular and Transverse Lines

1. Parallel, Perpendicular and Transverse Lines

What are the different types of lines? Where are they visible in the real world and how can you recognize them? Find out here and test your knowledge with a quiz.

Types of Angles: Vertical, Corresponding, Alternate Interior & Others

2. Types of Angles: Vertical, Corresponding, Alternate Interior & Others

In addition to basic right, acute, or obtuse angles, there are many other types of angles or angle relationships. In this lesson, we will learn to identify these angle relationships and discuss their measurements.

Triangles: Definition and Properties

3. Triangles: Definition and Properties

What makes a shape a triangle? In this lesson, we'll explore the definition of a triangle, then analyze the parts of triangles, including the vertices, base and height.

Classifying Triangles by Angles and Sides

4. Classifying Triangles by Angles and Sides

Not all triangles are the same. There are equilateral, isosceles and scalene triangles. Then there are right, acute and obtuse triangles. In this lesson, we'll learn how to classify triangles using their sides and angles.

Angles and Triangles: Practice Problems

5. Angles and Triangles: Practice Problems

Want more practice solving with angle pairs? How about more review for solving angles in triangles? Look no further. Get more practice here, and test your ability with a quiz.

Properties of Shapes: Quadrilaterals, Parallelograms, Trapezoids, Polygons

6. Properties of Shapes: Quadrilaterals, Parallelograms, Trapezoids, Polygons

Four-sided objects are more than just squares and rectangles. In this lesson, we'll discuss quadrilaterals, parallelograms and trapezoids. We'll also discuss polygons, objects that can have more sides than you can count.

What Are Polygons? - Definition and Examples

7. What Are Polygons? - Definition and Examples

Watch this video lesson to see how the shapes that you grew up with are all related. Learn why the shapes of bricks, stars, and street blocks are considered polygons while the sun, moon, and rolling hills are not.

Regular Polygons: Definition & Parts

8. Regular Polygons: Definition & Parts

What makes a polygon a polygon? And what shapes are considered polygons? In this lesson, find out the answers to these questions and more as we learn all about polygons and their parts.

Finding the Properties of Three-Dimensional Objects on the SAT

9. Finding the Properties of Three-Dimensional Objects on the SAT

Struggling with 3-D geometry problems on the SAT, like the problems about cubes and spheres? In this lesson, you'll learn how to crack them by breaking them down into more familiar 2-D shapes and solving from there.

Planes and the Polyhedron: Definition and Example

10. Planes and the Polyhedron: Definition and Example

Did you ever wonder what the pyramids in Egypt have to do with math? Watch this video to find out where in math a pyramid comes into play. Also, learn how flat, 2-dimensional shapes also come into play.
