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.
Study these two figures. Only the pair on the right is considered to be adjacent, angles c and d. Adjacent angles must share a common side and a common vertex, and they must not overlap each other. Vertical angles are pairs of angles formed by two intersecting lines. Vertical angles are not adjacent anglesâthey are opposite each other. In this diagram, angles a and c are vertical angles, and angles b and d are vertical angles. Vertical angles are congruent.
