The geometry is the measurement and the properties of points, lines, angles, planes and solids, as well as the relationships to each other. The following are some basic concepts related to geometry that will help you much to start with success, the study of this beautiful area. Segment: Is that part of a straight line between two points is marked on it. t line: Is that part of a straight line is somewhere a point (the end) indicated on it. The Grade is a unit of measurement symbolized . Therefore there are 360 in a complete revolution.

In the international system of measures, the unit of measure is the radian angle. The angles can be divided into different types based on the degrees they have. Thus, we can distinguish between four types of angles. In the next learning unit will explain the various classes. a right angle: it is formed by the junction of two perpendicular lines that form a quarter of a revolution, which is 90 . : An obtuse angle has a larger opening to the right angle, namely 180. : An acute angle has a smaller opening to the right angle.

is one whose sides are opposite rays, the angle is also half of a revolution, or 180 . To calculate the perimeter is necessary to know the length of all sides of the figure.
