Understanding Acute Angles – Definition, Examples, and Real-life Applications

Acute Angle

Any angle smaller than 90 degrees (1° to 89°)

An acute angle is a type of angle which measures between 0 and 90 degrees. It is an angle that is smaller than a right angle (90 degrees) but larger than a zero degree angle or a straight angle (180 degrees). The term acute is derived from the Latin word acutus which means sharp or pointed.

Acute angles can be found in various geometrical shapes such as triangles, rectangles, and polygons. In a triangle, an acute angle is one of the three angles that is less than 90 degrees. Acute angles can also be formed when two intersecting lines or two line segments meet at a point and create an angle that is smaller than 90 degrees.

Examples of real-life situations where acute angles are encountered are when measuring the height of a tree using a clinometer or when measuring the angle between the needle of a compass and the true north.

In summary, an acute angle is an angle which is less than 90 degrees and can be found in various geometrical shapes, and in many day-to-day situations.
