Question

from the information given below.find which of the point is between the other two.
D(P,R)=7,. D(P,Q)=10, D(Q,R)=3​

Answer 1

take d(P,Q) as point 1.

draw a line segment with P, R and Q points respectively and show the distance between the points as shown above.

add d(P,R) and d(Q,R).

the answer you get, mark it as point 2.

now write, from point 1 and point 2 d(P,Q) = d(P,R) + d(Q,R).

and therefore, point R is in between point P and point Q. and they are collinear.

^hope that helped.
