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. In other words, it is an angle that is smaller than a right angle.
To understand this concept, imagine a clock face where the 12 o’clock position represents a right angle (90 degrees) and the 6 o’clock position represents a straight angle (180 degrees). Any angle between the 12 o’clock position and the 6 o’clock position would be considered an acute angle because it is smaller than 90 degrees.
One way to identify an acute angle is to use a protractor. Place the protractor on the vertex (the point where the two rays of the angle meet) and measure the angle. If the measurement is less than 90 degrees, then it is an acute angle.
Acute angles are commonly found in everyday situations. For example, the angle formed by the hands of a clock at any given time is often an acute angle. If it is currently 3:00, the angle between the hour hand and the minute hand would be acute. Similarly, when you fold a piece of paper diagonally, the fold creates an acute angle.
Acute angles are important in various mathematical calculations and applications. They can be used in geometry to classify and measure angles, as well as in trigonometry to solve problems involving right triangles. Understanding acute angles helps in analyzing the relationship and properties of different angles and shapes.
