What is 180 degree angle? The angle which forms a straight line is chosen the 180-caste bending. In geometry, nosotros will be introduced to different types of angles, such equally acute bending, birdbrained angle, right angle, straight angle, reflex angle and full rotation. The angle which measures 180 degrees is named the straight angle. The other angles are given here: Astute angle: The angle which is more 0° and less than ninety° Right angle: The bending which is equal to ninety° Obtuse angle: The angle which is more than 90° merely less than 180° Reflex angle: The bending which is more than 180° Full rotation angle: The bending equal to 360° In this article, y'all will learn how to measure out the angles 180 degrees using a protractor, how to construct the 180 degree angle using a compass along with steps and structure images
