Analyze the union of adjacent angles
Using the Geometric Set Operations and Intersection and Union knowledge points
\[
\angle FGZ \cup \angle ZGH = \angle FGH
\]
Analyze the intersection of adjacent angles
Using the Geometric Set Operations and Intersection and Union knowledge points
\[
\angle FGZ \cap \angle HGZ = \vec{GZ}
\]
Analyze the union of rays sharing an endpoint
Using the Rays and Segments, Geometric Set Operations, and Intersection and Union knowledge points
\[
\vec{GF} \cup \vec{GZ} = \angle FGZ
\]
Analyze the intersection of rays sharing an endpoint
Using the Rays and Segments, Geometric Set Operations, and Intersection and Union knowledge points
\[
\vec{GF} \cap \vec{GZ} = G
\]
