Grade 9 pythagorean theorem

The two sides which come together in a right angle are called

• Hypotenuse

• Legs

• Adjacent

• Opposite

The lengths of the legs are usually called

• a and b

• c and d

• m and n

• x and y

The side across from the right angle is called the

• Hypotenuse

• Legs

• Opposite

• Adjacent

The relationship Pythagorus discovered is now called

• The Law of Sines

• The Law of Tangents

• The Pythagorean Theorem

• The Law of Cosines

The Pythagorean Theorem says, given the right triangle with legs a and b and hypotenuse c,

• c^2 = a^2 + b^2

• b^2 = a^2 + c^2

• a^2 + b^2 = c^2

• a^2 = b^2 + c^2
