The document discusses different types of angles found in a kitchen. It notes that the fan blades create acute angles under 90 degrees, while the stove supports create obtuse angles over 90 degrees. The refrigerator corner forms a right angle of exactly 90 degrees. The wood ridge creates a supplementary angle where two angles add up to 180 degrees. The complementary angle is two angles that add up to 180 degrees as well. The vertical cabinet angles are the same measure but on opposite sides. The straight angle measures 180 degrees.
