Answer:
(b, c)
Explanation:
The mid-point of two vertices or point is calculated by adding the respective coordinates of those points and then dividing by two. The x-coordinates will be added and then divided by 2 and then y-coordinates will be added and divided by 2.
So for the given question,
P(0,0)
Q(2a,0)
And
R(2b, 2c)
Mid-point of PR =( (0+2b)/2, (0+2c)/2)
=(2b/2, 2c/2)
=(b,c)
So the mid-point of PR is (b, c)
Last option is the correct answer..
