How do you solve for a missing side length in a right triangle using the Pythagorean theorem?

• Apply the Pythagorean theorem formula: a^2 + b^2 = c^2, where 'a' and 'b' are the known side lengths and 'c' is the hypotenuse. Solve for the missing side length by taking the square root of the result.

• Subtract the two known side lengths

• Multiply the two known side lengths

• Divide the two known side lengths

What is the Pythagorean Converse?

• A triangle is only a right triangle if the sum of the squares of the sides is less than the square of the longest side.

• The Pythagorean Converse states that all triangles are right triangles.

• If the sum of the squares of the sides of a triangle is not equal to the square of the longest side, then the triangle is a right triangle.

• If the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
