# Find the Distance Between the Following Pair of Point: (a, b), (− a, − b) - Mathematics

Find the distance between the following pair of point:(ab), (− a, − b)

#### Solution

Distance between (ab) and (− a, − b) is given by

l = sqrt((a-(-a))^2+(b-(-b))^2)

= sqrt((2a)^2 + (2b)^2)

= sqrt(4a^2+4b^2) = 2sqrt(a^2 + b^2)
