Question

Find the circumcenter of the triangle (-2,4) (-2,-1) (1,-1)

Answer 1

Answer:

( $-\frac{1}{2}$ , $\frac{3}{2}$ )  

Step-by-step explanation:

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

Coordinates of midpoint are

( $\frac{x_{1} +x_{2} }{2}$ , $\frac{y_{1} +y_{2} }{2}$ )

~~~~~~~~~~~~~~~~~~~~

The figure is right triangle.

The circumcenter is the middle of the hypotenuse.

( - 2, 4 )

( 1 , - 1 )

( $-\frac{1}{2}$ , $\frac{3}{2}$ )
