## What are the real world uses of a parabola?

When liquid is rotated, the forces of gravity result in the liquid forming a parabola-like shape. The most common example is when you stir up orange juice in a glass by rotating it round its axis. Parabolas are also used in satellite dishes to help reflect signals that then go to a receiver.

**Are parabolas a strong shape?**

Why is a parabola a strong shape? The parabola is considered such a strong shape because of its natural oval shape. Both ends are mounted in a fixed bearing while the arch has a uniformly distributed load. When an arch carries only its own weight, the best shape is a catenary.

### What are some applications of parabola in real life?

These principles work for light, sound, and other forms. This property is very useful in all the examples seen in the real world. A satellite dish is a perfect example of the reflective properties of parabolas mention earlier.

**Is it possible to have three supplementary angles?**

No, three angles can never be supplementary even though their sum is 180 degrees. Though the sum of angles, 40 o, 90 o and 50 o is 180 o, they are not supplementary angles because supplementary angles always occur in pair. The definition of supplementary angles holds true only for two angles.

#### Which is an example of a parabola shape?

Studies show that the shape is nearer to a parabola. The cables would have been hyperbolic, but when a uniform load (the horizontal deck) is present, they get deformed like a parabola. Take the example of any object thrown up in the air.

**How is the supplement of an angle obtained?**

The supplement of an angle is obtained by subtracting it from 180 degrees. Thus the angle that is supplementary to 84 degrees is 180 o – 84 o = 96 o What Angle is Formed if we Put the Supplementary Angles Together? When a pair of supplementary angles are put together, they form a straight angle.
