Question

question name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

One way to name an angle is by using the vertex. If the vertex of the angle is \(D\) and there are no other angles sharing the same vertex that would cause confusion, we can name the angle \(\angle D\).

Step2: Use three - point naming

Another way is to use three points. The angle can be named based on points on the rays forming the angle and the vertex. So it can be named \(\angle FDE\) (where \(D\) is the vertex and \(F\) and \(E\) are points on the two rays of the angle).

Answer:

\(\angle D\), \(\angle FDE\)
