Answer:
Midpoint of AB=(6,10) ,Midpoint of BC=(6,9) and Midpoint of CA=(-3,12)
Explanation:
Given that the points are A(-3,13), B(15,7) and C(-3,11)
To find the mid points :
To find midpoint of AB
Let
be the points A(-3,13),B(15,7) respectively
Midpoint of AB




Midpoint of AB=(6,10)
To find midpoint of BC
Let
be the points B(15,7),C(-3,11) respectively
Midpoint of BC




Midpoint of BC=(6,9)
To find midpoint of CA
Let
be the points C(-3,11),A(-3,13),respectively
Midpoint of CA




Midpoint of CA=(-3,12)
Therefore Midpoint of AB=(6,10) ,Midpoint of BC=(6,9) and Midpoint of CA=(-3,12)
