📐 Geometry Angle Reference
Vertical Angles
Vertical angles are opposite angles formed by two intersecting lines. They are always equal in measure.
Adjacent Angles
Adjacent angles share a common vertex and side but do not overlap. They may or may not be supplementary.
Corresponding Angles
When a transversal crosses parallel lines, corresponding angles are in the same relative position and are equal.
Alternate Angles
Alternate interior angles are equal when lines are parallel. Alternate exterior angles are also equal.
Supplementary Angles
Two angles that add up to 180°. Linear pairs are adjacent supplementary angles.
Complementary Angles
Two angles that add up to 90°. They don't need to be adjacent.
🏗️ Real-world Applications
Architecture
Understanding angles is crucial for designing stable structures, calculating roof pitches, and creating aesthetic designs.
Engineering
Mechanical engineers use angle calculations in machine design, force analysis, and motion planning.
Navigation
Pilots and sailors use angle calculations for course plotting and navigation using bearings.
Computer Graphics
3D rendering and game development rely heavily on angle calculations for lighting, shadows, and perspectives.
Note: This calculator provides angle measurements based on standard geometric principles. For critical applications, always verify calculations with professional tools.
