What is the Pythagorean Theorem?

• The Theorem that the sum of the squares of the
  lengths of the sides of a right triangle is equal
  to the square of the length of the hypotenuse.

3
Basic Terms A Triangle

• A basic shape in geometry A polygon with 3
  corners and 3 sides.

SIDE
4
Basic Terms A Right Triangle

• A right triangle is a one that has one angle that
  is 90 .

5
The lengths of the legs are usually called a and
b.
6
The length of the hypotenuse
is usually labeled c.
7
The Pythagorean Theorem says, given the right
triangle with legs a and b and hypotenuse c,

then

General Terms What is it used for

• If there is a right triangle with 2 known side
  lengths.
• Then with the Theorem you can calculate the 3rd
  side.

Quick Notes

• A and B in the Pythagorean Theorem are the two
  remaining sides. No specific side for either
  variable.
• C in the Pythagorean Theorem is always the
  hypotenuse.
• Review The hypotenuse is the side opposite of
  the right angle in a right triangle.
