Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

An angle can be named by its vertex. Here the vertex is point J, so one way to name the angle is $\angle J$.

Step2: Use three - point naming

We can also name the angle using three points on the rays and the vertex in the middle. So another way is $\angle MJL$ or $\angle LJM$.

Answer:

$\angle J$, $\angle MJL$
