Question
Prove that: PR = PQ + QR
Give a two-column proof
Hint:
Use Euclid’s Axiom
The correct answer is:
SOL – In the figure, we can see that PR coincides with
PQ + QR.
Acc. to Euclid’s Axiom, things which coincide with one another are equal to one another.
Hence Proved
NOTE – Alternative method
We can also prove using Segment addition postulate which states that if a line segment has two endpoints, A and C, a third point B lies on the line segment AC if and only if this equation AB + BC = AC
Since in figure given above, Q lies on the line segment PR Þ PR = PQ + QR.
