# The triangle

The triangle is given by three vertices:
A [0.0]
B [-4.2]
C [-6.0]
Calculate V (intersection of heights), T (center of gravity), O - center of a circle circumscribed

Correct result:

x1 =  -3.3333
y1 =  0.6667
x2 =  -3
y2 =  -1

#### Solution:

${y}_{1}=\frac{{A}_{y}+{B}_{y}+{C}_{y}}{3}=\frac{0+2+0}{3}=\frac{2}{3}=0.6667$
