The formula to verify a right angle in a triangle is the Pythagorean theorem: a² + b² = c², where 'a' and 'b' are the lengths of the two legs, and 'c' is the hypotenuse. This equation holds true if the triangle is right-angled.

FAQs & Answers

  1. How can I prove a triangle has a right angle? You can prove a triangle has a right angle by using the Pythagorean theorem formula a² + b² = c², where the sum of the squares of the legs equals the square of the hypotenuse.
  2. What does the Pythagorean theorem represent? The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse's length is equal to the sum of the squares of the other two sides' lengths.
  3. Can the Pythagorean theorem be used for any triangle? No, the Pythagorean theorem only applies to right-angled triangles where one angle is exactly 90 degrees.
