Question6. In the figure below, ray $\overrightarrow{E F}$ was constructed starting from rays $\overrightarrow{E D}$ and $\frac{\overrightarrow{E C}}{}$. By using a compass $D$ and $G$ were marked equidistant from $E$ on rays $\overrightarrow{E D}$ and $\overrightarrow{E G}$. The compass was then used to locate a point $F$, distinct from $E$, so that $F$ is equidistant from $D$ and $G$. For all constructions defined by the above steps, the measures of $\angle D E F$ and $\angle G E F$ :
