Aren’t most of us fascinated with geometrical shapes? One comes across an array of geometrical shapes in day-to-day life. The bed, glass, mirror, laptop, oven, and other items of daily use have distinct geometrical shapes. One might have often come across different foods or things which are triangular in shape. From the sandwiches you eat in breakfast, high-level geometrical calculations you do in school to the dangerous Bermuda triangle, almost everything is triangular. Let’s understand more about this geometric shape which is present at almost all sites in our vicinity.

A triangle is a three-sided and two-dimensional closed structure. It is a polygon with three corners, vertices and three angles joined together forming a closed structure.

Let’s explore the real-life examples of the triangle:

**1. Bermuda Triangle**

The Bermuda Triangle, also known as the Devil’s triangle, is a loosely defined triangular area in the Atlantic ocean, where more than 50 ships and 20 aircraft have said to be mysteriously disappeared. It is a vaguely defined triangular region between Florida, Bermuda, and Great Antilles.

**2. Traffic Signs**

Traffic signs form the most commonly found examples of the triangle in our everyday life. The signs are in equilateral triangular shape; which means that all three sides are of equal lengths and have equal angles.

**3. Pyramids**

Pyramids are the ancient monuments constructed by Egyptians. They are tetrahedral in shape, i.e., have four triangular sides which converge into a single point at the top. They still have remained a mystery to the humankind. Again, the shape of the pyramids is that of an equilateral triangle.

**4. Truss Bridges**

Truss bridges have supporting structures constructed in triangular shapes. Triangles are used in supporting the structure of the bridges because they evenly distribute the weight without changing the proportions. When force is applied on a rectangular shape, it will flatten out. The bridges used to be very weak and could not hold much weight before triangular shapes were incorporated in their structure.

**5. Sailing Boat**

Almost every boat nowadays have a triangular sail. In the early years, the sailing ships had a sail with a square design. By using a triangular sail design, it has become possible to travel against the wind using a technique known as tacking. Tacking allows the boat to travel forward with the wind at right angles to the boat.

**6. Roof **

The roofs of the houses are made in the triangle shape. The roof truss is an obtuse-angled triangle. In this type of triangle, any one of the three angles is more than 90 degrees. The roof truss is constructed because it doesn’t let water or snow to stand on the roof for a longer time.

**7. Staircase and ladder**

The construction of the staircase involves knowledge about right angles. The staircase is built in a triangular shape, mostly at right angle triangle. Moreover, the ladder when placed against the wall at any angle also makes a triangle.

**8. Buildings, Monuments, and Towers**

Many buildings are constructed in triangular shapes to make them more appealing and interesting. Towers including the network towers and the most famous Eiffel tower is also triangular in shape. The triangular shape gives strength to the tower since it forms a strong base. The Eiffel Tower is 1,063 feet tall. There are approximately 186 triangles in the Eiffel Tower.

**9. Finding the Height of a Pole or Mountain**

The concept of right angle comes in usage again whenever we have to find the angle of elevation or the height of a pole or a mountain. Moreover, we can also calculate the distance of the ship from the particular tower using a triangular geometry.

**10. Sandwiches or Pizza Slices**

Most of us start our day with the sandwiches which are triangular in shape. Our mothers make a sandwich in triangular shape because it looks more appetizing and because of the triangular shapes, the sandwiches come in handy. A study was conducted which said that triangularly shaped sandwiches are more preferred by children than the ones which are non-triangular in shape.

Thank you very much. It helped me for my project to write ten uses of triangle in daily life

Who has two thumbs and loves triangles

I love this link it helped so much

Thanks a lot! It helped for a video of mine!

good information with pics. Thankyou
