Answer: An angle is formed when two lines or surfaces meet at a point. You see angles around you every day, even if you don’t always notice them. Let’s understand this with three simple and real-life examples:
1. Open Door – An Example of an Obtuse Angle
Imagine you open your classroom door halfway. The open door forms an angle between the door and the wall. If the door is opened wide, the angle becomes more than 90 degrees, but less than 180 degrees. This is called an obtuse angle. So, the space between the open door and the wall is an everyday example of an obtuse angle.
2. Book Pages – An Example of an Acute Angle
When you slightly open a book, the pages form a sharp angle with each other. If the opening is small, the angle between the two pages is less than 90 degrees. This is called an acute angle. Opening the book pages is a perfect example of an acute angle!
3. Clock Hands at 3 O’clock – An Example of a Right Angle
Look at a clock when the time is 3 o’clock. The hour hand points at 3, and the minute hand points at 12. The angle between the two hands is exactly 90 degrees. This is called a right angle. Right angles are also found in the corners of tables, books, and walls.
Why Are Understanding These Examples Important?
Angles are all around us, in furniture, buildings, tools, and even nature. By looking at things like doors, clocks, and books, you can understand math in a fun and easy way. It also helps in learning measurement and geometry more clearly.
Learning about angles through real-life examples makes it easier to understand and remember. So, now as you understood bout the angles, you can keep observing the world around you to find many more angles around you.
