geometry - this is a very multi-faceted science.It develops logic, imagination and intelligence.Of course, because of its complexity and the large number of theorems and axioms, it is not always like schoolboys.In addition, there is a need to constantly prove their findings, using common standards and rules.Related

and vertical angles - is an integral component geometry.I'm sure many students simply adore them for the simple reason that their properties are clear and easy to prove.

Education angles

Any angle formed by the intersection of two lines or of two beams from a single point.They may be called either a single letter or three, which are sequentially designated point angle construction.

Angles are measured in degrees, and can (depending on their value) for different label.So, there is a right angle, acute, obtuse and detailed.Each of the names corresponds to a certain degree or measure of the gap.

island is called the angle whose measure does not exceed 90 degrees.

Blunt is an angle greater than 90 degrees.

angle is called direct in the case where it is a measure of degree 90.

In that case, when he formed one continuous line, and it is 180 degree measure, called deployed.

adjacent angles

angles with a common side and the second side which continues to each other, said to be adjacent.They can be both acute and obtuse.Crossing the line forms a straight angle adjacent angles.Their properties are as follows:

- sum of the angles is equal to 180 degrees (there is a theorem that proves it).Therefore, we can easily calculate one if the other is known.
- from the first section that are not adjacent angles may be formed by two blunt or two acute angles.

Because of these properties, it is always possible to calculate the measure-degree angle, having a value of another angle or, at least, the ratio between them.

Vertical viewing angles

parties which are an extension of each other are called vertical.As such the pair may make any of their varieties.Vertical angles are always equal.

They are formed by the intersection of the lines.Together with them are always present and adjacent angles.The angle may be simultaneously adjacent to one another and vertical.

When crossing an arbitrary line parallel lines are also considering several types of corners.This line is called the cross-section, and it forms the respective unilateral cross and lying angles.They are equal.They can be considered in the light of the properties that are vertical and adjacent angles.

Thus, the theme of the corners is quite simple and clear.All their properties are easy to remember and prove.Problem solving is not difficult as long as the angles corresponding numeric value.Even further, when will the study sin and cos, have to remember multiple complex formulas, their conclusions and consequences.Until then, you can just enjoy the easy puzzles in which you must find the adjacent angles.
