Question

The circumcenter of the triangle formed by the points(2,-5),(2,7),(4,7) is

Answer 1

Step-by-step explanation:

Only process

Put the triangle inside a circle such that the three vertices of the triangle are on the circumference of the circle now take the centre of the circle as

P(x,y)

name the three points of the triangle as A,Band C respectively.

Follow

PA=PB(by using distance formula equate them)

and PB=PC(by using distance formula do the same)

use the separate equations to find the values of x and y by using either elimination method or substitution method.

you will get the value of x and y separately . Find P. That's the circumcenter .
