2.  -What is the Pythagorean Theorem?
 a^2+b^2=c^2

3.  A- can be what ever number that is given
 B- can also be what ever number that is given.
 C- is ALWAYS going to be the hypotenuse.
The hypotenuse is found directly across from
the right angle.

4.  We use a right angle triangle.

5.  a^2+b^2=c^2

6.  a^2+b^2=c^2
 8^2+4^2=X^2
 64+16=x^2
 80=x
 X=8.9

7.  A=X2-X1
 B=Y2-Y1
 C=(X2,Y2),(Y1,Y1)

8.  = Ö(2 5)2 + (-2 -
6)2 ___________ = Ö(-3)2 +
(4)2 ________ = Ö9 +
16 ____ = Ö25 = 5

9.  (2,3),(1,7)
 D=(2- -1)^2+(3-7)^2
(3)^2 ( -4)^2
9 + 16=25
Square root of 25=5
