Choice 1
3(MC) = SC
Explanation:
The three medians intersect at the centroid, which is point M in this case. The intersecting medians subdivide themselves in the ratio 2:1
This means that SM is twice as long as MC. We can say SM = 2MC
Then by the segment addition postulate, we know that:
SC = SM + MC
SC = 2MC + MC
SC = 3MC
3(MC) = SC
So having three copies of MC glued together will form segment SC.
The same idea applies for the other medians also (EK = 3EM and RL = 3ML).
