Students should be able to:
- identify and classify right, acute, and obtuse angles.
- recognize the angles formed and the relationship between the angles when two lines intersect.
You can learn a lot about angles by looking at letters.

Angles Mini-Movies on Your SMARTBoard
A SmartBoard mini-movie is a simple (most involve only a click of the mouse), interactive animation that teachers can download and use on their interactive whiteboards. From there, the movies can be inserted into their SMART Notebook presentations. Each mini-movie is a dynamic Flash file, similar to the same files that are already included in SMART Notebook's resources.
