Answer:
PR = 2*36 = 72
SU = (1/2)54 = 27
RS = 36
Step-by-step explanation:
By the Midpoint Theorem, the argent that connects midpoints of the sides of a triangle equals half the parallel side. That said,
- PR is the full side that corresponds to midpoint segment TU. Therefore it's twice the distance of TU.
- SU is the midpoint segment that corresponds to fill side PQ and therefore half the distance.
- RS is half the the length of PR since S is the midpoint.
