Formula to find the mid-point is
.
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,
.
=
![((2a)/(2) ,(0)/(2) )](https://img.qammunity.org/2019/formulas/mathematics/middle-school/k74fr2b6bx6s7l2t4hsnaiv71o9oralair.png)
=(a,0).
So, mid-point of HG is (a, 0).
