When you find out the angle between the two plains, you can make out how much force it is required from your car to be able to climb the other plain.

Also, you will be able to make decisions based on the calculations even before you start construction. A lot of times construction of dams and bridges depends on the angles on which the inclination needs to be made. If during the calculation, the results are not desirable, the project will not proceed further, thus, saving a lot of time and money at the same time.

**2. What are the Different Types of Angles?**

There are a number of angles which you are going to learn in RS Aggarwal class 9 maths ch 7 from Vedantu. There's a zero angle in which both the arms of the angle are in the same plane and the same position. After that, there's an acute angle which is more than 0 degrees but it's less than 90 degrees. This type of angle can be seen in bridges inclination on which you take your car on.

Then there is a 90-degree angle which is also known as a right angle, and you can find this angle in your home. The angle between your floor and your room walls is a 90-degree angle. Lastly, we have an obtuse angle which is more than 90 degrees but less than 360 degrees. You can find an obtuse angle in ramps, stairs and escalators in the shopping malls with respect to the floor.

**3. How can we Introduce the Concept of Angles to a Student by Using Some Activities?**

A great way to introduce students with the different types of angles is by making a fun activity which introduces them to angles. One of the great ways is by asking them to make a shape of the first alphabet which comes in their name. Once the alphabet is made using the scale, ask students to take a ruler to find out the angles which are present in the first letter of their name.
