What Properties or characteristics or similar triangles could be used to prove the Pythagorean theorem?
Zolol [24]
Well, in order to prove the Pythagorean theorem, every triangle you are using has to have one right angle (90-degree angle), and the side opposite to it will be called the hypothenuse. The remaining two triangles will be acute angles (<90 degrees), and the sides opposite to them are called sides/catheti.

Answer:

\left( x-2\right)^{2}  +\left( y-6\right)^{2}  =12

Step-by-step explanation:

Formula ………………………………………………………………………

The equation of a circle with center (a , b) and radius r is :

\left( x-a\right)^{2}  +\left( y-b\right)^{2}  =r^{2}

===================

Now ,let’s apply what we have learnt:

The equation of the circle with center (a , b) = (2 , 6) and radius r = 2√3 is :

\left( x-2\right)^{2}  +\left( y-6\right)^{2}  =\left( 2\sqrt{3} \right)^{2}

\Longleftrightarrow \left( x-2\right)^{2}  +\left( y-6\right)^{2}  =12

\text{Note :} \left( 2\sqrt{3} \right)^{2}  =2^{2}\times \sqrt{3}^{2} =4\times3=12

use the points (1998,13.60) and (2003,19.00) to write the slope intercept form of an equation for the line of fit shown in the s
Reika [66]
Find the slope: m=(19.00-13.60)/(2003-1998)=1.08
so we have y=1.08x +b
next, use the point (2003, 19.00) to find b:
19.00=1.08*2003 +b =>b=-2144.24
so the equation is y=1.08x-2144.24
