Horizontal line segment \(AC\) is
above horizontal line segment \(EJ\).

Point \(B\) is on \(AC\) and a ray starting at B divides
straight angle \(ABC\) into two angles:
one angle measures \(60\degree\) and
the other angled is labelled \(x\).

Line segment \(BD\) intersects \(EJ\) forming four quadrants around the
point of intersection. The angle forming the top-left quadrant measures
\(90\degree\) and the angle forming the
bottom-right quadrant (or opposite quadrant) is labelled \(w\).

Line segment \(HI\) intersects \(EJ\) at a different point, forming four
quadrants around this point of intersection. The angle forming the
top-left quadrant measures \(90\degree\). Line segment \(FG\) also passes through this point of
intersection and divides the top-right and bottom-left quadrants into
two parts. In the top-right quadrant, the angle between \(EJ\) and \(FG\) measures \(40\degree\). In the bottom-left quadrant,
the angle between \(EJ\) and \(FG\) (opposite the \(40\degree\) angle) is labelled \(y\), and the angle between \(FG\) and \(HI\) is labelled \(z\).
