Coordinates Of A Point In Space

Coordinates of A, B, Care (2, 3) (4, -1), (4, 3). respectively.
Slope

m_1

of BC is

%5Cfrac%7B3%20-(-1)%7D%7B4-4%7D%20%3D%5Cinfty

Slope

m_2

of AC is

%5Cfrac%7B3%20-3%7D%7B4-2%7D%20%3D%200

%5Ctherefore%20%5C%3A%5C%3A%5C%3A%5CDelta%20ABC

is right angled at C (4, 3)

%5Ctherefore

Circumcentre of

%5CDelta%20ABC

is the mid-point of the hypotenuse AB which is

%5Cleft(%20%5Cfrac%7B4%20%2B%202%7D%7B2%7D%20%2C%20%5Cfrac%7B3%20-1%7D%7B2%7D%20%5Cright)

i.e..,

(3%2C1)
