Angles - Acute, Obtuse, Straight and Right - Math is Fun
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).

1.7: Introduction to Angles - K12 LibreTexts
2020年11月28日 · Angles. When two rays meet at their endpoints, they form an angle. Depending on the situation, an angle can be named with an angle symbol \(\angle\) and its vertex, or by three letters. If three letters are used, the middle letter should be the vertex. The angle below could be called \(\angle B\) or \(\angle ABC\) or \(\angle CBA\).

Angles Study Guide - CK-12 Foundation
Angles are formed when two rays share an endpoint. Angles are classified by their measure. Acute angles measure less than 90°, right angles measure exactly 90°, obtuse angles measure between 90 to 180°, and straight angles are 180°. Angles also have relationships with each other.
