Project of group 2: Nine-Point CircleGiven 3 points in the coordinate system:A(0, 0), B(4, 0), C(1, 3). • Find the coordinates of the 3 midpoints M1, M2, M3 of the 3 sides. • Find the coordinates of 3 midpoints I1, I2, I3 of segments IA, IB, IC (I is the orthocenter). • Find the coordinates of the 3 feet F1, F2, F3. • Show that the 9 points are one the same circle. Find the center and radius of the circle. Write equation of this circle in center-radius form. C I3 F1 M2 M1 F2 I I2 I1 A B M3 F3
