Pythagorean Theorem

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). It can be expressed as: a² + b² = c².

A right triangle is a triangle that has one angle measuring 90 degrees.

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Yes, because 3² + 4² = 5² (9 + 16 = 25).

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Yes, because 9² + 12² = 15² (81 + 144 = 225).

To simplify a radical means to express it in its simplest form, removing any perfect square factors.

x = √119.

True.

x = 2√22.
