• Tangent (tan) of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
  • Trigonometry starts with understanding triangles and their properties. A triangle's sides are related by trigonometric ratios. The most common ratio involves sides opposite, adjacent to, and the hypotenuse of a right-angled triangle. These ratios - sine, cosine, and tangent - are crucial for determining unknown sides or angles.
