> In geometry, which type of angle is greater than 90 degrees, but less than 180degrees?And the answer: obtuse. Photo credit: Impressive Interior Design[https://www.impressiveinteriordesign.com/architecture-showcase-buildings-with-sharp-angles/].In geometry, there are three basic types of angles. An acute angle is smallerthan 90 degrees, a right angle equals 90 degrees, and an obtuse angle measureslarger than 90 but less than 180 degrees.Angles make up most everything that surrounds us. They give integral structureto manmade creations like buildings and homes, but they also occur in abundancein nature. Where a tree meets the soil, a (close to) 90 degree angle is formed.Some types of rock, such as basalt, can form naturally occurring columns wherein180 degrees or less can be measured in its sides. However, measuring angles is most helpful in the field of architecture. Manyroof trusses display obtuse angles, seen most prominently in the ridge of ahouse's roof. Right and acute angle trusses create an unusual shape compared tothat of an obtuse angle. Architecture also examines corresponding angles, whichare those created by the convergence of several lines from different directions.Meanwhile, acute angles are helpfully found in many everyday objects. Astethoscope that doctors use to listen to your heartbeat contains acute angles,while landscape professionals often use hedge shears and tree-trimming toolsthat open to an acute angle. In your home, acute angles can be found in a pairof tweezers, salad tongs, a miter box, houseplant leaves and even a pair of openscissors. How many acute and obtuse angles can you find in your own home? Learn more aboutthese angles here [https://interiorarchitects.com/geometry-the-angle/].
