Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

We can name the angle using the vertex point. Since the vertex of the marked angle is \(K\), one way to name it is \(\angle K\).

Step2: Use three - point naming

We name the angle using three points where the middle point is the vertex. The marked angle can be named as \(\angle IKJ\) (the order of the non - vertex points \(I\) and \(J\) around the vertex \(K\) can be interchanged).

Answer:

\(\angle K\), \(\angle IKJ\)
