Answer 2

Step-by-step explanation:

$\Large{\red{\underline{\underline{\sf{\blue{Given:}}}}}}$

• Two circles have centre O and O' respectively which intersects at P.
• CD || OO'

 ‎ ‎ ‎ ‎ ‎ ‎ ‎

$\Large{\green{\underline{\underline{\sf{\red{To\:prove:}}}}}}$

• CD = 2OO'

 ‎ ‎ ‎ ‎ ‎ ‎ ‎

$\Large{\red{\underline{\underline{\sf{\pink{Solution:}}}}}}$

 ‎ ‎ ‎ ‎ ‎ ‎ ‎

From the fig. we can see that CD is formed by joining of two cords of two circles,

i.e $\tt CD\:=\:CP\:+\:PD$

 ‎ ‎ ‎ ‎ ‎ ‎ ‎

We know that,

$\sf{\blue{\underline{\red{diamter\:is\:the\:longest\:chord\:in\:any\:circle.}}}}$

$\sf \implies CP\:=\:CD\:=\:Diametre\:of\:circle$

 ‎ ‎ ‎ ‎ ‎ ‎ ‎

we know that,

$\tt Diametre\:=\:2\times Radius$

$\sf \implies CP\:+\:CD\:=\:2O\:+2O'$

$\sf \hookrightarrow CD\:=\:2OO'$
