Geometry

__**Lesson 1 - Angles at a Point **__ Try the activity from the website below. Kung Fu Angles Open the files below for information on the properties of angles at a point.
 * __Geometry __** Geometry is a part of mathematics concerned with questions of size, shape and relative position of figures and with properties of space. Geometry is one of the oldest sciences, and is used in construction, fencing, carpentry, computer graphics, computer-aided design, robotics, medical imaging, structural engineering, protein modelling, physics, chemistry and biology.
