An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. It is larger than a right angle, which measures exactly 90 degrees. Obtuse angles can be found in various shapes and objects, such as in certain types of triangles, specifically obtuse triangles, where one angle is obtuse. In everyday life, you can observe obtuse angles in various places, like in the design of certain furniture or in the layout of some buildings. Understanding obtuse angles is important in fields like geometry and architecture, where precise measurements are crucial for creating functional and aesthetically pleasing designs.
