acute angle
An acute angle is an angle that measures less than 90 degrees
An acute angle is an angle that measures less than 90 degrees. It is a type of angle that is smaller than a right angle (90 degrees) and larger than a straight angle (180 degrees). In simple terms, an acute angle is any angle that is “sharp” or “narrow” and does not extend beyond the measure of a right angle.
To visualize an acute angle, you can think of it as the angle formed by two lines or line segments that are close together and do not diverge or intersect in such a way that they form a larger angle. For example, if you draw two line segments that meet at a common point and the angle they form is less than 90 degrees, then that angle is considered an acute angle.
Acute angles are commonly encountered in various geometric and trigonometric problems. They are also present in our daily lives, such as the acute angles formed by the hands of a clock at different times or the acute angles of a triangle.
To measure an acute angle, you can use a protractor, a tool specifically designed for measuring angles. By aligning the vertex (common point) of the angle with the protractor’s center and matching one of the angle’s sides with the protractor’s baseline, you can determine the angle’s measurement in degrees. If the angle measures less than 90 degrees, it is an acute angle.
