WebIllustrated definition of Triangle: A 3-sided flat shape with straight sides. It is a polygon. WebIn the above section, we read that an angle that measures less than 90 degrees, i.e. less than a right angle is an acute angle. The examples of acute angle degrees are 63°, 31°, 44°, 68°, 83°, 85°. Hence, the acute angle degree lies within the ranges from 0° to less than 90°. Here are a few diagrammatic representations of acute angles.
