Types Of Degrees Angles Acute Right Obtuse Straight Reflex Full The names of basic angles are acute angle, obtuse angle, right angle, straight angle, reflex angle and full rotation. an angle is geometrical shape formed by joining two rays at their end points. an angle is usually measured in degrees. there are various types of angles in geometry. angles form the core part of the geometry in mathematics. There are 5 types of angles based on measurement: an acute angle is an angle that lies between 0° and 90°. examples: 35°, 80°, 72° etc. an obtuse angle is an angle which lies between 90° and 180°. examples: 135°, 150°, 122°, etc. a right angle is an angle that precisely measures 90 degrees.
Acute Straight Right Obtuse And Reflex Angles Properties The different types of angles based on their measurements are: acute angle an angle less than 90 degrees. right angle an angle that is exactly 90 degrees. obtuse angle an angle more than 90 degrees and less than 180 degrees. straight angle an angle that is exactly 180 degrees. Acute angle – less than 90° at the vertex. right angle – between 90° and 180°. obtuse angle – exactly 90° at the vertex. straight angle – exactly 180°. reflex angle – between 180° 360°. complete angle – 360°. below is an explanation of each of the different types of angles with their figures: acute angle. Parts of an angle. the corner point of an angle is called the vertex. and the two straight sides are called arms. the angle is the amount of turn between each arm. how to label angles. there are two main ways to label angles: 1. give the angle a name, usually a lower case letter like a or b, or sometimes a greek letter like α (alpha) or θ (theta).

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. The obtuse angle is bigger than the right angle and the acute angle. an obtuse angle measures between ninety degrees (90°) to one hundred and eighty degrees (180°). one of the ways to calculate obtuse angle is if we know the value of the acute angles. for instance, obtuse angle = 180° – value of acute angle. straight angle:.
