Types Of Angles Acute Obtuse Straight Right Reflex Angles The obtuse triangle has an obtuse angle (an obtuse angle has more than 90°). in the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle. since the total degrees in any triangle is 180°, an obtuse triangle can only have one angle that measures more than 90°. Learn about the six types of angles based on magnitude (acute, obtuse, right, straight, reflex and full) and the two types of angles based on rotation (positive and negative). also, explore the pairs of angles, angles formed by transversal and frequently asked questions.
Types Of Angles Mathematics Notes Teachmint When two rays or lines meet at a common point, an angle is formed and each angle differs in its measure. there are various types of angles in geometry, like, acute angle, obtuse angle, right angle, reflex angle, and straight angle. for example, an acute angle is an angle that is less than 90° and an obtuse angle is one that is greater than 90°. 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). Types of angles. based on their measurements, here are the different types of angles: an acute angle measures less than 90° at the vertex. an obtuse angle is between 90° and 180°. a right angle precisely measures 90° at the vertex. an angle measuring exactly 180° is a straight angle. a reflex angle measures between 180° 360°. 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.

There are several different types of angles. acute angles – an acute angle is an angle that is less than 90∘ 90∘ and greater than 0∘ 0∘. obtuse angles – an obtuse angle is an angle greater than 90∘ 90∘ but less than 180∘ 180∘. reflex angles – a reflex angle is greater than 180∘ 180∘ but less than 360∘. 360∘. right. 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.
