acute angle
An acute angle is defined as an angle that measures less than 90 degrees
An acute angle is defined as an angle that measures less than 90 degrees. In other words, if two lines intersect and form an angle that is smaller than a right angle (which measures 90 degrees), then that angle is considered acute.
For example, if you have two lines that intersect each other and the angle formed between them measures 30 degrees, it would be classified as an acute angle. Similarly, if the angle measures 75 degrees or any value less than 90 degrees, it would also be considered acute.
Acute angles are commonly found in many geometric shapes and figures, such as triangles. In a triangle, all three angles must be acute because the sum of all angles in a triangle is always 180 degrees. Therefore, in a triangle, each angle has to be less than 90 degrees, making them acute angles.
Understanding acute angles is important in various areas of mathematics, including geometry and trigonometry. Knowledge of acute angles allows us to measure and analyze angles within shapes, determine the classification of triangles, calculate trigonometric functions such as sine, cosine, and tangent, and much more.
