Question

if l is the midpoint of tj, what must be true?
t is also the midpoint of jl
tl = lj
jl = tj

Explanation:

Step1: Recall the definition of a midpoint

A midpoint of a line segment divides the segment into two equal parts.

Step2: Apply the definition to segment TJ

If \(L\) is the midpoint of \(TJ\), then by the definition of a midpoint, the lengths of \(TL\) and \(LJ\) are equal. So \(TL = LJ\).

Answer:

\(TL = LJ\)
