Angle relationships used in the puzzle:
Vertical angles: Vertical angles are opposite angles formed by the intersection of two lines. Vertical angles are always congruent, meaning they have the same measure.
Complementary angles: Complementary angles are two angles that add up to 90 degrees.
Supplementary angles: Supplementary angles are two angles that add up to 180 degrees.
Solving the puzzle:
Angle AGB: Angle AGB is a vertical angle to angle DCE. Therefore,
