Learn what an obtuse angle is, how to measure it, and how to identify it in geometry and real life. Find out the difference between obtuse and acute angles, and how to solve problems involving obtuse triangles. Learn what an obtuse angle is, how to identify it, and its properties. See real-life examples of obtuse angles and how to measure them. Explore obtuse angle triangles and their characteristics. Obtuse Angles can be classified according to their measure. An obtuse angle is an angle that measures more than a right angle but less than a straight angle . So, an obtuse angle has a measure between 90° and 180°. Obtuse Angle Definition In Mathematics, “ an obtuse angle is an angle which is greater than 90 ° and less than 180 °”. In other words, an obtuse angle is between a right angle and a straight angle . Let us consider the below example,
