The Rule of Pythagoras

In mathematics the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a .......................... triangle.

The Pythagoras' theorem states that the area of the square whose side is the ........................................ (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

The Pythagorean theorem states that the sum of the squares on the ...........................of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)

The Pythagorean ............................ states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)

In a right triangle, the ....................................... is the longest side,

The hypotenuse of a right triangle is always the side ............................ the right angle.

The .......................................... of a right triangle is always the side opposite the right angle.

The two sides of a right triangle are called the ........................... of the triangle.

Because a ............................. triangle is made up of two legs and a hypotenuse, a right triangle can also be called a hypotenuse-leg (or HL) triangle.

An isosceles right triangle is a right triangle that consists of two ..................... length legs.
