$\large\color{red}\mathcal{Hello\:Friend}$

$\bf{Given\:that}$:- OX=1/2 XY,
PX=1/2 XZ and OX=PX.

Using Euclid Axiom: 'If the halves of one thing is equal to another then the Wholes are also equal to each other.'

So, OX=1/2 XY and PX=1/2 XZ....... also OX=PX...... Let eq. 1

Therefore, Using the above Axiom in Eq. 1
we get;
XY = XZ.
