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.
A regular hexagon (all sides and angles congruent) has no right angles, although it's possible that an irregular hexagon could. All hexagons have six sides and six angles. The angles must add up to 720Â°. So it would be possible to have as many as 5 angles equal 90Â° (5 x 90Â° = 450Â°), and one angle equal 270Â° (450Â° + 270Â° = 720Â°). <br /> Take a rectangle then cut a rectangular notch at one of the corners. You now have 6 sides and 6 angles.
