The side pieces will not be parallel when lapped with top section ends
because the corresponding angle formed by the side pieces are not equal.
Reasons:
The given angle on each end of the window frame = 37°
The angle at the top ends of the side pieces = 50°
According to angle addition postulate, we have;
Angle formed when the top section and the side pieces lap = 37°+ 50° = 87°
Therefore;
The angle formed by the left side piece is 87° below the positive x-axis
direction, while the corresponding angle formed by the right side piece is
1.3° below the positive x-direction, such that the two side pieces are
inclined towards each other, and given that the corresponding angles are
not equal, the side pieces are therefore, not parallel.
