The document summarizes the Pythagorean theorem and distance formula. It states that the Pythagorean theorem equation is a^2 + b^2 = c^2, where a and b are the legs of a right triangle and c is the hypotenuse. An example problem demonstrates solving for the missing side of a right triangle. The distance formula is defined as the square root of (x2-x1)^2 + (y2-y1)^2, and a worked example finds the distance between two points.

PYTHAGOREAN THEOREM

2. What is Pythagorean Theorem,
and what do the variables stand
for?
 Pythagorean Theorem has an equation that
goes along with it.
 a^2+ b^2=c^2
 The variables stand for the two legs (a^2 and
b^2) and the c^2 is the hypotenuse. The
hypotenuse is always c^2.
 You use a right triangle for this equation

3. Example on how to solve the
problem
3 5
x
3^2+x^2=5^2 x
9+x^2=25 x
-9 -9
Square root of 16= 4

4. What is distance formula?
 Square root of (x2-x1)^2+(y2-y1)^2 is the
equation for the distance formula
 To solve a distance formula problem you do 3
simple steps
1. Label the points
2. Put them into the distance formula
3. Do the math

5. Example of the distance
formula problem
(3,2) and (6,4)
x1 y1 x2 y2
(6-3)^2+(4-2)^2
3^2+2^2
9+4
13
Square root of 13= 3.60
