Question
Point M is the mid-point of segment AB. If AB = 8.6 cm, then find AM.
Solution
M is the midpoint of seg AB.
AM will be half of AB that is AB is equal to 8.6cm. so AM will be equal to half of 8.6cm that is 4.3cm.
AB = 8.6cm
AM = `8.6/2 = 4.3 "cm"`

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`
