Lines and Angles

Lines and Angles:

Very early in school we were taught that a minimum of two points are required to draw a Line,there are different types of lines.Let us now look at the different types of lines,all lines have different properties,

Properties of line:

Line: A line can illustrate between two points only.

Parallel lines: These are straight lines in the similar plane and do not meet together. They may extend in any direction

Intersection: The intersection of two lines meet single point called as intersection point.

Similarly now let us learn about angles:

An angle is the amount of rotation point of intersection of two lines in order to make one line into correspondence with other. An angle is denoted by theta. Angles are usually measured in degree, radiations or gradations. The sign conversion the anticlockwise rotation is considered to be positive and clockwise rotation is considered to be negative.The other way to understand about angles is by studying the properties of angles.The size of an angle is calculated in degrees. When we say the angle ABC we denote the definite angle objects.. If we desire to talk regarding the size or compute of the angle in degrees, we must say 'the compute of the angle ABC- often written m∠ABC. However, many times we will see ∠ABC=34°. It should say m∠ABC=34°.

• Vertical angles: The vertical angles are opposite angles formed by two intersecting lines and congruent.
• Complementary angles: Angles are two angles whose measure, when added together, equal 90°.
• Supplementary angles: Angles are two angles whose measures, when added mutually, equal 180°.

• Adjacent angles: Angles share a general side and a general vertex and do not overlap. Two non-adjacent angles formed by transversal crossing parallel lines are alternate interior angles if they are between the parallel lines and on opposite sides of the transversal.
• Alternate exterior angles: Angles are a pair of angles located in outside a set of parallel lines and on opposite sides of the transversal.
• Corresponding angles: Angles are two angles in corresponding positions formed by a transversal crossing two lines.
