About This Chapter

Review lines and angles with this chapter in preparation for success on the ISTEP+ Grade 7 Math exam. The video lessons in this chapter will ensure students are familiar with these mathematical concepts.

ISTEP+ Grade 7 Math: Lines & Angles - Chapter Summary

This chapter was designed to ensure students are ready to answer questions about lines and angles on the ISTEP+ Grade 7 Math exam. Our lessons provide the chance to review:

  • Line segments and rays
  • Lines that are parallel, perpendicular and transverse
  • Acute, obtuse, right, straight and supplementary angles
  • Transversal, vertical and complementary angles

An interactive quiz supports each lesson, allowing students to practice solving questions involving angles and lines. The lessons also focus on helping familiarize students with the mathematical vocabulary words they may be tested on and our expert instructors are available to answer any questions that may arise

Line Segments & Rays: Definition & Measurement

1. Line Segments & Rays: Definition & Measurement

Watch this video lesson to learn the difference between a line segment and a ray. You will also learn how to measure and add line segments. Learn why you can't measure or add a ray.

Parallel, Perpendicular and Transverse Lines

2. 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.

Angles Formed by a Transversal

3. Angles Formed by a Transversal

When you have a pair of parallel lines and a transversal, something very interesting happens to the angles that are formed. You can see this happen in real life at street intersections and such. Watch this video lesson to learn about all of this.

What is an Acute Angle? - Definition, Description & Examples

4. What is an Acute Angle? - Definition, Description & Examples

In this lesson, you'll learn what makes an angle acute and see a few different examples of them. After the lesson, you can test your new knowledge with a brief quiz.

What is an Obtuse Angle? - Definition & Examples

5. What is an Obtuse Angle? - Definition & Examples

In this lesson, you'll learn what angles, right angles, and obtuse angles are; you'll see a few examples of different obtuse angles. Test your knowledge with a brief quiz once you've completed the lesson.

What is a Right Angle? - Definition & Formula

6. What is a Right Angle? - Definition & Formula

In this lesson, you will learn about the properties that identify right angles. You will also discover where right angles can be found and learn about what makes them so useful. You can then test your knowledge with a quiz.

What is a Straight Angle? - Definition & Example

7. What is a Straight Angle? - Definition & Example

This lesson will be an explanation of what a straight angle is. It will include several examples that fully demonstrate the straight angle in contrast with other angles.

Supplementary Angle: Definition & Theorem

8. Supplementary Angle: Definition & Theorem

There are many important angle pairs in geometry. In this lesson, we'll learn about supplementary angles, including what they are, where they are used, and why you need to know about them.

Vertical Angles & Complementary Angles: Definition & Examples

9. Vertical Angles & Complementary Angles: Definition & Examples

Special angles make your life easier. Learn how you can use the properties of special angles to help you find the measurements of missing angles in this video lesson.
