To find the degree of a triangle, sum the internal angles, which always equal 180 degrees. If two angles are known, subtract their sum from 180 to find the third angle. For example, if one angle is 50° and another is 60°, the third would be 180° - (50° + 60°) = 70°.

FAQs & Answers

  1. What are the internal angles of a triangle? The internal angles of a triangle sum up to 180 degrees regardless of the triangle's type.
  2. How do you find the third angle of a triangle? To find the third angle, subtract the sum of the known angles from 180 degrees.
  3. What is the formula for the sum of angles in a triangle? The formula states that the sum of the internal angles in a triangle is always 180 degrees.
  4. Can a triangle have more than three angles? No, a triangle, by definition, always has exactly three angles.
