Q6 of 29 Page 7

Answer the questions with the help of figure 1.14.


i. State the points which are equidistant from point B.


ii. Write a pair of points equidistant from point Q.


iii. Find d(U, V), d(P, C), d(V, B), d(U, L).

i. Points A and C or Points P and D

ii. Points U and L or Points R and P


iii. d (U, V) = 5 – (-5) = 5 + 5 = 10


d (U, V) = 10


d (P, C) = 4 – (-2) = 4 + 2 = 6


d (P, C) = 6


d (V, B) = 5 – 2 = 3


d (V, B) = 3


d (U, L) = -3 – (-5) = -3 + 5 = 2


d (U, L) = 2
