Using a pair a of ruler of compasses only construct triangle xyz such that xy= 5cm,xz=4cm and yz=6cm
1. construct the mediator of line yz
2. Construct the mediator of line xz
3.Locate O the point of intersection of line mediators of line YZ And Xy
With centre o and rdius Oy draw acircle
Draw it for me
draw YZ
draw circles at Y and Z with radii 4 and 5
Where the two intersect is X.
I assume you can construct a ⊥ bisector, so the medians are doable.
Now draw the final circle.
