Question

Use the segment addition postulate to write three equations using the diagram below

Answer 1

Answer:

$PQ + QR = PR$ => equation 1

$RS + ST = RT$ => equation 2

$PR + RT = PT$ => equation 3

Step-by-step explanation:

Points P, Q, R, S, and T are collinear therefore, the following equations can be written based on the segment addition postulate:

$PQ + QR = PR$ => equation 1

$RS + ST = RT$ => equation 2

$PR + RT = PT$ => equation 3

More equations can actually be written from the diagram given using the segment addition postulate. Such as:

$PQ + QR + RS + ST = PT$
