Draw or Cut two similar squares with sides
units long.
Draw or cut four pairs of similar right triangles with side lengths as indicated in the diagram.
Now arrange the similar triangles at the corners of the squares such that the sides
of one similar triangle plus the side
of a second similar triangle coincides with the length of the square.
We do another arrangement of the similar triangles. This time arrange another 4 similar triangles in the opposite corners, such that each pair forms a square.
Now comparing the two different arrangements we got two different areas that are equal.
The area of the uncovered squares in the first arrangement is 
The area of the two uncovered squares in the second arrangement is 
Equating the two areas gives the Pythagoras Theorem

Note that
is the hypotenuse,
and
are two shorter sides of the similar right triangles.
Answer:
1st Graph: 2 circles are shown
Step-by-step explanation:
In order to have a solution set, the 2 graphs need to intersect each other. All the graphs but the 2 circles intersect and have a solution. Therefore, our answer is the 1st Graph.
Answer:
y=-3(x-9)
Step-by-step explanation:
Point slope form is y-y1=m(x-x1)
x1=9
y1=0
m=-3
plug it all in!
y-0=-3(x-9)
y=-3(x-9)
Hope this helps!
