Let's recall.
We have studied the following expansion formulae in previous s
(i) (a + b)2 = a + 2ab + b2, (ii) (a - b) = (? - 2ab +
(iii) (a + b) (a - b) = (- 62
Ise the above formu

11Centroid of a triangle. The coordinates of the centroid are simply the average of the coordinates of the vertices. So to find the x coordinate of the orthocenter, add up the three vertex x coordinates and divide by three. Repeat for the y coordinate.
