Write an equation for median AE.
The 3 lines
Find the coordinates of P. Verify algebraically that the lines all intersect at P.
Triangle ABC has vertices at (0,0),(5,5), and (10,1),. Kiran calculates the point of intersection of the medians using the following steps:
Draw the triangle.
Calculate the midpoint of each side.
Draw the medians.
Write an equation for 2 of the medians.
Solve the system of equations.
Use Kiran’s method to calculate the point of intersection of the medians.
