Draw a right angled XYZ. Draw it's medians and show their point of concurrence by G.
Steps of construction:
(i) Draw a right angled $\Delta X Y Z$.
(ii) Draw the perpendicular bisector PQ of side $\mathrm{YZ}$ that intersect $\mathrm{YZ}$ at $\mathrm{L}$.
(iii) Join XL. XL is the median to the side YZ.
(iv) Draw the perpendicular bisector TU of side $Z X$ that intersect $Y Z$ at $M$
(v) Join YM. YM is the median to side $Z X$.
(vi) Draw the perpendicular bisector RS of side XY that intersect XY at N.
(vii) Join ZN. ZN is the median to the side $X Y$. Hence, $\Delta \mathrm{XYZ}$ is the required triangle in which medians $\mathrm{XL}, \mathrm{YM}$ and $\mathrm{ZN}$ to the sides $\mathrm{YZ}, \mathrm{ZX}$ and $\mathrm{XY}$ respectively intersect at G.
The point G is the centroid of $\Delta X Y Z$.
