Congruent acute or obtuse angles

Angles are congruent if they have the same angle measure in degrees. These scissors contain congruent acute angles (drawn on in purple). They are acute because they both have measurements less than 90 degrees. The angle at which the scissors open both have the same dimensions and shape, making them congruent. Scissors are a househeld object and are used to cut things. I took this photo myself and scissors are part of the metal fabrication industry.
