Point T is on line segment S U ‾ SU . Given T U = 16 TU=16 and S T = 4 , ST=4, determine the length S U ‾ . SU .

Answer 1

Draw a picture of your line and label the distances as given

Since T is a point on SU then SU would be a combination of the distances you are given.

TU = 16

ST = 4

SU = ST + TU

Answer 2

S-------------T-----------------------------------U

4 16

The Segment Addition Postulate is:

ST + TU = SU

4 + 16 = ?
