Acute angle is the angle less that 90o degrees

What are Angles?

An angle is a geometric shape formed when two lines or line segments meet at a common point. The point where the lines or line segments meet is called the vertex of the angle. Angles are measured in degrees and can be classified into different types based on their measurements.

Acute Angle

An acute angle is an angle that measures less than 90 degrees. It is a small angle that is formed between two lines or line segments that are close to each other. The term "acute" comes from the Latin word "acutus," which means "sharp" or "pointed." In other words, an acute angle is a sharp or pointed angle.

Characteristics of Acute Angles

- Measurement: An acute angle always measures less than 90 degrees. It can range from 0 degrees (a zero angle) to just under 90 degrees.
- Shape: Acute angles have a sharp or pointed shape. They look like a "V" or a "V" that is not opened wide.
- Location: Acute angles are found in various objects and shapes in our daily life. For example, the corners of a square or a triangle are acute angles.
- Properties: Acute angles have certain properties, such as being complementary to obtuse angles (an angle that measures greater than 90 degrees but less than 180 degrees) and supplementary to other acute angles (two angles that add up to 180 degrees).

Examples of Acute Angles

- A right angle, which measures exactly 90 degrees, is not considered an acute angle because it is equal to the maximum limit for an acute angle.
- An angle measuring 30 degrees is an acute angle.
- An angle measuring 60 degrees is also an acute angle.
- An angle measuring 89 degrees is very close to being a right angle, but it is still considered an acute angle.

Conclusion

In summary, an acute angle is a small angle that measures less than 90 degrees. It has a sharp or pointed shape and is found in various objects and shapes. Understanding different types of angles, including acute angles, is important in geometry and can help us analyze and describe the world around us.
