Just take the average of the three vertices' coordinates. So if they are (a,b),(c,d),(e,f), the centroid is at ((a+c+e)/3, (b+d+f)/3).

You parrallel bisect the three sides of the triangle...... where those three lines meet is the centroid of the triangle
To know you're right you should b able to draw a circle, starting from the centroid, and it should touch the three sides or your triangle

draw the heights of the triangular.
The intersection point will be the center of the circle.
the radius is the distance between the center and the foot of a height.
