· The Pythagorean theorem is named after
the Greek mathematician; Pythagoras.
· Who by tradition is credited with its
discovery and proof.
· His theorem is written as a formula.
What Is The Hypotenuse?
· C² represents the hypotenuse multiplied
by itself (squared).
· The hypotenuse is the side of a right
triangle opposite the right angle.
side in a
Working It Out
· Write out the formula:
a² + b² = c²
· Put the numbers in the write place, and label unknown
sides as a letter.
5² + 12² = C²
· Find the squares of the known numbers:
25 + 144 = 169
· As the hyp. is being squared, to find the real value we
must square root it:
169 = 13…read more
· Let's see if it really works using an example. A
"3,4,5" triangle has a right angle in it, so the
formula should work.
· Let's check if the areas are the same:
3² + 4² = 5²
· Calculating this becomes:
9 + 16 = 25
YES!!! It works!…read more
