7th Grade - Lines and Angles

Today we began our first geometry unit with a close look at lines and angles. We looked at various types of angles and the relationships between angles. Use your textbook to remind you of some of the angles we discussed in our lesson today, and to help you complete your homework.

Also, recall the properties of angles we discussed:

Below are a few videos in case you need reminders.
