# 10 Examples of Triangles in Real Life

Most of us are fascinated by geometric shapes. In everyday life, one comes across an array of geometric shapes. Beds, glasses, mirrors, laptops, ovens, and other everyday items have different geometric shapes. One often comes across various foods or objects which are triangular in shape. From the sandwich, you eat for breakfast and high-level geometric calculations to the dangerous Bermuda Triangle, almost everything is triangular. Let’s understand more about this geometric shape which is present in almost all the sites around us. Now we are discussing some examples of triangles in Real Life.

A triangle is a three-dimensional and two-dimensional closed structure. It is a polygon whose three angles, vertices, and three angles join together to form a closed structure.

## Let’s explore the examples of triangles in real-life:

### (1) Sandwiches or Pizza Slices

Most of us start our day with a triangular sandwich. Our mothers make a sandwich in triangular shape because it looks more appetizing and a triangular shape makes sandwiches useful. A study was conducted that states that triangular-shaped sandwiches are preferred by children more than non-triangular sandwiches.

### (2) Finding the Height of a Pole or Mountain

The concept of right angle comes into use again whenever we need to find the angle of elevation or the height of a pole or mountain. Moreover, we can also calculate the distance of the ship from a certain tower using a triangular geometry.

### (3) Buildings, Monuments, and Towers

Many buildings are made in triangular shapes to make them more interesting and attractive. Towers are also triangular, including the Network Tower and the most famous Eiffel Tower. The triangular shape gives strength to the tower as it forms a strong base. The Eiffel Tower is 1,063 feet tall. There are about 186 triangles in the Eiffel Tower.

### (4) Staircases and Ladders are examples of triangles

Stair construction involves knowledge of right angles. The staircase is built in a triangular shape, mostly in a right triangle. Furthermore, a ladder placed at any angle against a wall also forms a triangle.

### (5) **Modern Roof**

The modern roof of the house is made in a triangular shape. A roof truss is an obtuse triangle. In such a triangle, any of the three angles is greater than 90 degrees. The roof truss is designed as it does not allow water or snow to stand on the roof for long periods of time.

### (6) Sailing Boats are examples of triangles

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

### (7) Truss Bridges

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

### (8) Pyramids are Examples of Triangles

The pyramids are ancient monuments built by the Egyptians. They are tetrahedral in shape, i.e., have four triangular faces that converge to a single point at the apex. They still remain a mystery to mankind. Again, the pyramids are shaped like equilateral triangles.

### (9) Traffic Signs

Traffic signs constitute the most common examples of triangles in our daily lives. The symbols are in the form of equilateral triangles; Which means all three sides are of equal length and have equal angles.

### 10. 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 are reported to have mysteriously disappeared. It is a vaguely defined triangular area between Florida, Bermuda, and the Great Antilles.
