cevian ratio explore
Find out how the cevian BY is cut by another cevian AX, which is determined by the ratios CX:XB and AY:YC.
You may modify these ratios more easily by using the square grid (as shown in the silent demo below). These ratios will be maintained even when you drag A.
Check more to show details.
Go to other activities in this chapter of the GeoGebra Book to get some hints about deriving YQ:QB.
