Final answer:
The included angle for line segments jl and kl is ∠l, as l is the common endpoint between the two segments.
Step-by-step explanation:
The question pertains to geometry and involves identifying an included angle. In geometry, the included angle between two line segments (in this case jl and kl) refers to the angle that is directly between them. Considering the segments are named jl and kl, the letter l is shared between them, indicating it's their common endpoint. Therefore, the included angle would be the angle at point l, which is ∠l.
