If you asked us to tap into the eighth-grade geometry students hidden deep within our personas to recall the difference between obtuse or acute angles, we’re not so sure we’d be able to. What we can tell you, as we hearken back to the days of learning of angles, degrees, and hypotenuses, is that we are seriously loving their resurgence in the design world. These abnormal angles are so unexpected yet remarkably understated. They’re clean without being harsh, playful without featuring polka dots or pink, and as sophisticated without the pretense. How smart are the lines in this fabulous accent chair? And that chandelier is to die for. If you’re looking for a fresh way to update your décor without committing to a crazy fad, a lesson in geometry may be just what you need.
