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) 2. or by the three letters on the shape that define the angle, with the middle letter being where the angle actually is (its vertex).
Learn about the different types of angles in geometry, such as acute, obtuse, right, straight, reflex and full angles. See how to measure, classify and compare angles based on magnitude, rotation, direction and pairs.

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°.
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°.
3 sie 2023 · An angle can be named in two ways: Method – 1: The angle symbol, followed by the three points that define the angle. The middle letter is the vertex. So the above figure can be written as ∠XOY or ∠YOX. Method – 2: Just by writing the vertex. It is written as ∠O.
28 gru 2022 · An angle consists of three parts: the arms, the vertex, and the angle: Vertex : The vertex is the point where two rays (or line segments) meet. Arms : The arms are the sides of the angle.
