Question Analysis

The main focus is to use the markings in the diagram and the Angle Bisector Equidistant Theorem to find the measure of ∠FEG.

Key Concept Explanation

The Angle Bisector Equidistant Theorem states that if a point lies on the angle bisector of an angle, then it is equidistant from the two sides of the angle. Conversely, if a point is equidistant from the two sides of an angle, then it lies on the angle bisector. Equal - length markings on the perpendicular segments from a point to the sides of an angle can imply the presence of an angle bisector.

Step - by - Step Solution

1. Observe the equal - length markings on  and , and that , .

By the converse of the Angle Bisector Equidistant Theorem, since the distances from point  to the two sides of the angle formed at
