USEFUL FACTS ABOUT ANGLES By the Maths Learning Centre, University of Adelaide The Basics When angles share a vertex and fill one side of a line, they add to 180°. When angles share a vertex and fill the space around a point, they add to 360°. When two lines cross, opposite angles are. The angle symbol, followed by three points that define the angle, with the middle letter being the vertex, and the other two on the legs. So in the figure above the angle would be ∠ ABC or ∠ CBA. So long as the vertex is the middle letter, the order is not important. This far-from-exhaustive list of angle worksheets is pivotal in math curriculum. Whether it is basic concepts like naming angles, identifying the parts of an angle, classifying angles, measuring angles using a protractor, or be it advanced like complementary and supplementary angles, angles formed between intersecting lines, or angles formed in 2D shapes we have them all covered for students.
