Find coordinates of midpoint of the segment joining points (0, 2) and (12, 14)
उत्तर
Let A(x1, y1) = A(0, 2), B (x2, y2) = B(12, 14)
Let the co-ordinates of the midpoint be P(x, y).
∴ By midpoint formula,
x = `(x_1 + x_2)/2 = (0 + 12)/2` = 6
y = `(y_1 + y_2)/2 = (2 + 14)/2 = 16/2` = 8
∴ The co-ordinates of the midpoint of the segment joining (0, 2) and (12, 14) are (6, 8).

From the figure given alongside, find the length of the median AD of triangle ABC. Complete the activity.
Solution:
Here A(–1, 1), B(5, – 3), C(3, 5) and suppose D(x, y) are coordinates of point D.
Using midpoint formula,
x = `(5 + 3)/2`
∴ x = `square`
y = `(-3 + 5)/2`
∴ y = `square`
Using distance formula,
∴ AD = `sqrt((4 - square)^2 + (1 - 1)^2`
∴ AD = `sqrt((square)^2 + (0)^2`
∴ AD = `sqrt(square)`
∴ The length of median AD = `square`
