In mathematics, the term “obtuse” is often used to describe an angle

In mathematics, the term “obtuse” is often used to describe an angle. An obtuse angle is an angle that is greater than 90 degrees, but less than 180 degrees. In other words, it is an angle that is wider than a right angle (90 degrees), but not as wide as a straight angle (180 degrees).

To better understand obtuse angles, let’s take a closer look at different types of angles:

1. Acute angle: An acute angle is an angle that measures less than 90 degrees. It is narrower than a right angle.

2. Right angle: A right angle measures exactly 90 degrees. It is formed when two lines intersect and create a 90-degree angle, forming a square corner.

3. Obtuse angle: An obtuse angle measures greater than 90 degrees, but less than 180 degrees. It is wider than a right angle but not as wide as a straight angle.

4. Straight angle: A straight angle measures exactly 180 degrees. It is a straight line and forms a half-circle.

To further illustrate, imagine a clock face. At 12 o’clock, there is a straight angle of 180 degrees. At 3 o’clock and 9 o’clock, there are right angles of 90 degrees. Any angle between 90 degrees and 180 degrees, such as 100 degrees or 150 degrees, would be considered an obtuse angle.

It is essential to understand angle measurements and terms like obtuse to solve various geometric problems, calculate distances, or determine the position of objects in space.
