If H is the orthocenter of `DeltaABC` and if `AH = x, BH = y, CH = z`, then `a/x+b/y+c/z=`

If H is the orthocenter of Delta ABC and if AH=x,BH=y,CH=z, then (a)/(x)+(b)/(y)+(c)/(z)=

If H be orthocentre of DeltaABC and mid point of AH, BH, CH are respectively P, Q, R then prove that H is also the orthocentre of DeltaPQR and DeltaPQR-DeltaABC .

If in Delta ABC , the distance of the vertices from the orthocenter are x,y, and z then prove that (a)/(x) + (b)/(y) + (c)/(z) = (abc)/(xyz)

If x = y^(a), y = z^(b) and z = x^(c), compute abc.

If x,y and z are in A.P ax,by and cz in G.P and a, b, c in H.P then prove that x/z+z/x=a/c+c/a
