Angle Calculator
Calculate angles, convert between degrees and radians, find complementary and supplementary angles, and solve triangle angles. A comprehensive tool for geometry, trigonometry, and math applications.
Step 1: Angle Input
Understanding Angles
An angle is formed by two rays (arms) with a common endpoint (vertex). Angles are measured in degrees (°), radians, or gradians. A full circle is 360°, 2π radians, or 400 gradians.
Step 2: Angle Operations
About Angle Operations
Complementary angles sum to 90°, supplementary angles sum to 180°, and triangle interior angles sum to 180°. Trigonometric functions (sin, cos, tan) relate angles to side ratios in right triangles.

Angle Conversion Formulas
Degrees to Radians: radians = degrees × π/180
Radians to Degrees: degrees = radians × 180/π
Degrees to Gradians: gradians = degrees × 400/360
Gradians to Degrees: degrees = gradians × 360/400
