Solve each of the following question using appropriate Euclid’s axiom: In the Fig. 5.11, if OX=0.5XY, PX=0.5XZ and OX = PX, show that XY = XZ.
Given that:
OX = 0.5 XY, PX = 0.5 XZ, OX = PX
To prove: XY = XZ
OX = 0.5XY ; PX = 0.5 XZ
2OX = XY … (1) ; 2PX = XZ … (2)
OX = PX … (3) (Given)
Euclid axiom says that things which are double of the same things are equal to one another.
Hence from equation (1), (2), (3)
2OX = 2PX
XY = XZ
Hence proved.
