To find the angle of a triangle, use the fact that the sum of all internal angles in a triangle is always 180 degrees. If you know two angles, subtract their sum from 180 to find the third angle. For example, if you have angles of 50° and 60°, the third angle will be 180° - (50° + 60°) = 70°. For more complex scenarios, such as involving side lengths, use trigonometric laws like the Law of Sines or Cosines.

FAQs & Answers

  1. What is the sum of the angles in a triangle? The sum of all internal angles in a triangle is always 180 degrees.
  2. How do I find the missing angle in a triangle? Subtract the sum of the known angles from 180 degrees.
  3. What is the Law of Sines? The Law of Sines relates the sides of a triangle to its angles and helps in calculating unknown angles or sides.
  4. Can I calculate angles using side lengths? Yes, you can use trigonometric laws like the Law of Sines or Law of Cosines for calculations based on side lengths.
