Triangle Theorems

You may find this question challenging:Given the three points A = [-3, 5], B = [ 5,4] and C = [ 4,4], consider the triangle AABC , and let M be the point on AC s0 that BM is the altitude through B perpendicular to AC . Likewise let N be the point on AB s0 that CN is the altitude through C perpendicular to AB(diagram not to scale)Find MM =ii) Find N :N = Note: in Maple notation the point 03,3 is entered as [1/2 ,3/4]Challenge (worth points): iii) It is known that the three altitudes of any triang
