Question

In the above diagram identify the points which are equidistant from point U.

• A. R and Q
• B. R and L
• C. R and P
• D. R and A

Answer 1

The correct option is A R and Q

If points X and Y are equidistant from point Z then d(X, Z) = d(Y, Z)
In the given question point U is -5 so d(U, R) = d(R, U) = -5 - (-6) = 1 and d(Q, U) = -4 - (-5) = 1
$\therefore$ d(R, U) = d(Q, U)

Hence, points R and Q are equidistant from point U.
