The document discusses the Pythagorean theorem and distance formula. The Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. It is used to find the length of the third side of a right triangle when two sides are known. The distance formula is used to find the distance between two points in a plane by taking the square root of the sum of the squared differences between their x- and y-coordinates. Examples of applying both the Pythagorean theorem and distance formula are provided.
2. QUESTIONS
What is the Pythagorean Theorem?
The Pythagorean Theorem is when you have to find
the third leg of the shape
-What do the variables stand for? The variables
stand for the third leg/side of the triangle
-What type of triangle do we use the theorem for?
We use a right triangle to find the theorem.
3. EXAMPLE
132+ 52 = x2
13
169+25=x2
5 194=x2
Do the square root of
194= x2
13.93=x
4. DISTANCES FORMALS QUESTIONS
-What is the Distance Formula? The distance
formula is when you have point and you find the
square root to get the answer to the problem
-What steps do you follow to use the distance
formula?
X2 – X1
Y2 - Y1
Than you should be done by add the numbers
together than do the square root and you have your
answer.
