This guide aims to prepare students for class discussions on geometric rotations. It covers foundational concepts, including what a rotation is and the necessary elements to understand it—such as center, object, direction, and angles. The guide explains how to calculate new coordinates after rotating points 90 and 180 degrees, both clockwise and counterclockwise. Students are encouraged to complete the warm-up exercises and assigned homework from Kuta's page on rotation of shapes to reinforce their understanding of these critical geometry concepts.

Warm Up 10/1/12 • Complete 2.5 Warm Up in your packet • Be prepared to discuss in class
Rotations • What is a rotation? • In order to complete a rotation, what do you need to know? Center? Object? Direction? How far?
Rotate this point 90 degrees clockwise? New coordinates? Rule?
Rotate this point 90 degrees counter- clockwise? New coordinates? Rule?
Rotate this point 180 degrees ? New coordinates? Rule? Does clockwise or counterclockwise matter with 180 degrees?
