Question

raj correctly determined that ray lh is the bisector of ∠gli. which information could he have used to determine this? ∠glh≅∠ilm m∠klm = 5m∠ilm m∠gli = 2m∠glh m∠gli=\frac{1}{2}m∠glh+\frac{1}{2}m∠hli

Explanation:

Step1: Recall angle - bisector definition

An angle - bisector divides an angle into two equal - measure angles. If ray $LH$ is the bisector of $\angle GLI$, then $m\angle GLH=m\angle HLI$ and $m\angle GLI = m\angle GLH+m\angle HLI=2m\angle GLH$.

Answer:

C. $m\angle GLI = 2m\angle GLH$
