Types Of Angles Acute Obtuse Straight Right Reflex Angles Learn how to measure angles in degrees using a protractor and a circle. find out the meaning of 360 degrees, the degree symbol, and the types of angles. Learn what an angle is, how to measure and classify it, and see real life examples of angles. explore the parts of an angle, types of angles, and how to construct an angle using a protractor. Angles are formed when two lines intersect at a point. the measure of the 'opening' between these two rays is called an 'angle'. it is represented by the symbol ∠. angles are usually measured in degrees and radians, which is a measure of circularity or rotation. angles are a part of our day to day life. engineers and architects use angles for. A = 90 °. obtuse angle. 90 ° < a < 180 °. straight angle. a = 180 °; the rays go in opposite directions. reflex angle. a > 180 °. full rotation angle. a = 360 °; looks like a zero degree angle, but one ray rotates exactly 360 ° to go in the same direction and the other.
