1. Pythagorean Theorem: In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. 2. Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. 3. Angle Sum Theorem: The sum of the interior angles of a triangle is always 180 degrees.

FAQs & Answers

  1. What is the Pythagorean Theorem? The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
  2. What does the Triangle Inequality Theorem state? The Triangle Inequality Theorem explains that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side.
  3. How do I calculate the angles in a triangle? To calculate the angles in a triangle, use the Angle Sum Theorem, which states that the sum of the interior angles is always 180 degrees.
  4. Why are triangle theorems important? Triangle theorems are crucial in geometry for solving problems related to triangle properties, proving other geometrical concepts, and real-world applications.
