Answer 1

Formula to find the mid-point is

`((x_(2)+x_(1))/(2) ,(y_(2)+y_(1))/(2) )`.

We need to find the mid-point of HG where H(0,0) and G(2a,0). So, now we can plug in x1=0, y1=0, x2=2a and y2=0 in the above formula to get the answer. So, mid-point of HG is,

`((0+2a)/(2) ,(0+0)/(2) )`.

=
`((2a)/(2) ,(0)/(2) )`

=(a,0).

So, mid-point of HG is (a, 0).
