The statistical mean can also be used to interpret statistical data. Some important properties make statistical mean very useful for measuring central tendency. Since Xi - X is the distance from a given number to the average. The numbers to the left of the mean are balanced by the numbers to the right of the mean.
In review, vertical angles are angles formed by the intersection of two lines while alternate interior angles, alternate exterior angles, corresponding angles and consecutive interior angles are formed by the intersection of two lines and a transversal.
In this section you will learn constructing angles. Construction in Geometry means to draw shapes, angles or lines accurately. In constructing-angles, mostly we use compass and ruler.Construction of Angles equal to a given angle Draw an angle of measure 70. Make a copy of it using ruler and compasses.n this section you will learn constructing angles. Construction in Geometry means to draw shapes, angles or lines accurately.
