Answer:
Step-by-step explanation:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
Examples of line segments include the sides of a triangle or square. More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or otherwise a diagonal. When the end points both lie on a curve such as a circle, a line segment is called a chord (of that curve).

See attached image.
In the proof we see that ∠EGF is congruent to ∠HGK because they are vertical angles. We also see that KG is congruent to FG because G is the midpoint. Additionally we have that ∠F is congruent to ∠K because they are alternate interior angles. We have two angles and the side between them, or ASA.
