Geometry Rotations LHS

Enrollment is Closed

Welcome to a lesson on rotations!

You are going to participate in a lesson on rotations. Recall that you previously learned two types of transformation: reflections and translations. Rotations are the third type of transformations you will learn about. You are most likely familiar with rotations in everyday life, for example an ice skater spinning. In this lesson, you will learn how to rotate a two dimensional figure using a ruler and protractor, and how to rotate 90 and 180 degrees about the origin. The lesson will prepare you for an activity in which you will create an animation flip book with a partner.

Ms. Elaine McGeown

Hello! I am a math teacher at Lowell High School. I began working at LHS in 1996. I have a bachelor’s degree in math and a master’s degree in education, both from the University of Massachusetts, Lowell. I’m always searching for innovative methods of engaging students in active learning. I have two sons, 33 and 30 years old (now you’re doing some math!). I’ve lived in the Lowell area my entire life. When I’m not working, I love to kayak, bicycle, mountain climb, snow ski (not very well), and ice skate.

Frequently Asked Questions

Do I need to use a textbook?

Yes, you will refer to your text book, Prentice Hall Geometry (2004), Chapter 12, Sections 1, 2, and 3.

What if I can't get the internet at home?

You have several options. You can go to the library before or after school, use my computer before or after school, or ask a relative or friend.
