#### You may not feel it, but the Earth is consonantly rotating on an axis. The old record player rotates a record on a turn table. Rotation is turn around in a circle on a center. When a geometric figure rotates, it does the same thing. The distance from the center point of the figure always remains the same. A rotation can happen in either direction. The direction is likened to an analog clock. We term it clockwise or counterclockwise. We do not spend a lot of the curriculum learning how to calculate the time a rotation takes, but we thought we would mention it because it will help you better understand what you are studying. The rotation calculation starts by understanding the circumference of the object. This is a difficult measure to calculate if the object is asymmetric this is where physics can be more of friend. Once you have the circumference you just divide the distance the object would need to cover to make a rotation and divide that by the circumference.

These worksheets show you a number of different ways to better understand the movement along an axis and how to measure it. We also offer you a better understanding of how to identify an axis that the objects you are studying or observing can pivot off of. We will also find different measures of figures including length of sides and angles. These worksheets explain how to use similar triangles to find the measure of the angle in an image or the images rotation.
