Why Angles Matter And Their Real-Life Examples

  Introduction  An  angle  is formed when two rays are joined together at a common point. The common point here is called node or vertex and the two rays are called  arms of the angle . The angle is represented by the symbol ‘ ∠ ’. The word angle came from the Latin word “ Angulus ” . Learn more about lines and angles here. The angle is usually measured in degrees, using a protractor. Degrees 30°, 45°, 60°, 90°, 180° shows different angles here. The types of angles  are based on the values of angles in degrees.  We can also represent angles in radians, i.e., in terms of pi (π). 180 degrees is equal to π in radians. Different Types of Angles and Names There are 10 Different Type of Angles:  Acute Angle : Measures less than 90° . Right Angle : Measures exactly 90° . Obtuse Angle : Measures more than 90° but less than 180° . Straight Angle : Measures exactly 180° . Reflex Angle : Measures more than 180° but less than 360° . F...
