1. Two of your friends‚ Matt and Karen‚ both run to you to settle a dispute. They were working on a math problem‚ and got different answers. Wisely‚ you decide to look at their work to see if you can spot the source of confusion.

Taviana Webb Period 1 Culminating Task #1 Rotation: The rotation transformation is where you turn a figure about a given point. The point that the obtated about can be inside the figure or anywhere outside it. The amount of rotation is called the angle of rotation and is measured in degrees. You can rotate shapes or figures on a coordinate grid. Each quadrant differs in degrees when working with rotations. Going clockwise the first quadrant is 90 degrees ‚ the second quadrant is 180 degrees

A movement is a self-contained part of a musical composition or musical form. While individual or selected movements from a composition are sometimes performed separately‚ a performance of the complete work requires all the movements to be performed in succession. A movement is a section‚ "a major structural unit perceived as the result of the coincidence of relatively large numbers of structural phenomena. Classification of Movements From a gymnastic point of view movements are divided into Active
