PT is 2 units in length.
In a triangle, the centroid is a point of concurrency where the three medians intersect.
Each median divides the opposite side into two segments, with the ratio of 2:1.
If PQ is a median and T is the centroid, then PT is one-third of PQ. Therefore, if PQ = 6, then:
PT = (1/3) * PQ
= (1/3) * 6
= 2
So, PT is 2 units in length.
