👉 Angles in geometry, particularly those studied in high school and beyond, are defined as the figures formed by two or more line segments that share a common endpoint called the vertex. The key properties of angles include their measures, which are typically expressed in degrees, and their relationships to each other, such as complementary angles (summing to 90°), supplementary angles (adding to 180°), and vertical angles (formed by intersecting lines and always equal). Special types include right angles (90°), acute angles (less than 90°), obtuse angles (greater than 90° but less than 180°), and straight angles (180°). Understanding these concepts is crucial for solving problems in trigonometry, architecture, and various fields requiring spatial reasoning.
