Answer to Problem 39WE

The points C,G and H are collinear (proved)

Explanation of Solution

Given information :

  ΔQRS With vertices Q(6,0),R(12,0) and S(0,12)

Formula used :

  the slope of the line =yy1xx1

Calculation :

The point of centroid G is (2,4)

The point of circumcenter C is (3,3)

The point of orthocenter H is (0,6)

The slope of line CG

  =3432=11=1

The slope of line GH

  =4620=22=1

The slope of line CH

  =3630=33=1

Therefore, the slope of CG,GH and CH is 1

Hence, the points C,G and H are collinear (proved)

b.

To determine

To proof : GH=2GC

Answer to Problem 39WE

  GH=2GC(proved)

Explanation of Solution

Given information :

  ΔQRS With vertices Q(6,0),R(12,0) and S(0,12)

Calculation :

The distance of G from H

  GH=(20)2+(46)2GH=(2)2+(2)2GH=4+4GH=8

The distance of G from C

  GC=(32)2+(34)2GC=(1)2+(1)2GC=1+1GC=2

Therefore,

  GHGC=82=222=2

Therefore, GH=2GC

Therefore, the distance of G from H is equal to the twice of the distance of G from C

Hence, GH=2GC(proved)
