To get clear concept on how to find the midpoints between two given coordinate points student’s can practice the questions given in the worksheet on finding midpoint.
We know that the average distance between the two given points is known as the midpoint. Midpoint can be represented by any letter, for example M, N, O, P etc,.
Let us recall the formula for finding the midpoint between any two given points as follows;
Suppose, (x₁, y₁) and (x₂, y₂) be the coordinates of the points P and Q respectively and R, the midpoint of the line segment PQ. Then, the coordinates of R are ((x₁ + x₂)/2, (y₁ + y₂)/2).

(i) (3, 5) and ( 1,  7)
(ii) (7,  8) and (3, 4)
(iii) (a,  b) and ( a, b)
(iv) (l, m) and (l + m, l  m).
2. (i) One extremity of a linesegment is the point (3,  2) and the middle point of the linesegment is the point ( 2, 3). Find the coordinates of the other extremity.
(ii) A diameter of a circle has the extreme points (7, 9) and ( 1,  3). What would be the coordinates of the centre ?
(iii) AB is' a diameter of a circle having centre at C; if the coordinates of A and C are (6,  7) and (5,  2), find the coordinates of B.
