Ch 6: Properties of Geometric Shapes & Angles

About This Chapter

Refresh your knowledge of the shapes and angles used in geometry with this chapter, including information and practice problems involving measurement. These lessons and quizzes can help you get the best score you can on an upcoming test or homework assignment.

Properties of Geometric Shapes & Angles - Chapter Summary

Our instructors will explain the properties of squares, rectangles, rhombuses and triangles. You will learn how to make important calculations such as perimeter, area and circumference. The Pythagorean theorem will also be introduced, along with its practical applications.

Your study will continue with a review of similar triangles, as well as parallel, transverse and perpendicular lines. The different types of angles and how they relate to triangles is also included. This chapter will show you how to:

  • Compare the properties of shapes, including rhombuses, squares and rectangles
  • Identify an isosceles triangle
  • Calculate the perimeter and area of triangles and rectangles
  • Find the area and circumference of a circle
  • Describe and utilize the Pythagorean theorem
  • Tell the difference between parallel, perpendicular and transverse lines
  • Differentiate between types of angles

Our mobile-friendly lessons and quizzes can be reviewed at any time, seven days a week. Each lesson is accompanied by a printable transcript so you can make a copy to review offline. Use the quizzes and chapter tests to gauge how well you understand the topics covered in the lessons, and feel free to contact our instructors if you have questions as you work through the chapter.

Properties of Shapes: Rectangles, Squares and Rhombuses

1. Properties of Shapes: Rectangles, Squares and Rhombuses

What's the difference between a square and a rectangle? What about a rhombus and a square? In this lesson, we'll look at the properties of these shapes.

Properties of Shapes: Triangles

2. Properties of Shapes: Triangles

Isosceles, equilateral and obtuse, oh my! These are terms for triangles. But, what do they mean? In this lesson, we'll explore the properties of triangles and take a closer look at the different types of triangles you may encounter.

Perimeter of Triangles and Rectangles

3. Perimeter of Triangles and Rectangles

Without realizing it, we calculate and use the perimeter of triangles and rectangles in regular everyday situations. Learn more about the perimeter of triangles and rectangles in this lesson, and test your knowledge with a quiz.

Area of Triangles and Rectangles

4. Area of Triangles and Rectangles

How do you find out the area of rectangles and triangles? Learn how in this lesson! We'll look at the formulas, then practice solving problems for each shape.

Circles: Area and Circumference

5. Circles: Area and Circumference

Understanding how to calculate the area and circumference of circles plays a vital role in some of our everyday functions. They serve as the foundation for operating with three-dimensional figures. Learn more about the area and circumference of circles in this lesson.

The Pythagorean Theorem: Practice and Application

6. The Pythagorean Theorem: Practice and Application

The Pythagorean theorem is one of the most famous geometric theorems. Written by the Greek mathematician Pythagoras, this theorem makes it possible to find a missing side length of a right triangle. Learn more about the famous theorem here and test your understanding with a quiz.

How to Identify Similar Triangles

7. How to Identify Similar Triangles

Similar triangles have the same characteristics as similar figures but can be identified much more easily. Learn the shortcuts for identifying similar triangles here and test your ability with a quiz.

Applications of Similar Triangles

8. Applications of Similar Triangles

Similar triangles are used to solve problems in everyday situations. Learn how to solve with similar triangles here, and then test your understanding with a quiz.

Parallel, Perpendicular and Transverse Lines

9. 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

10. 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.
