KHA TV. 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. 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.

It is a vaguely defined triangular region between Florida, Bermuda, and Great Antilles. 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. Pyramids are the ancient monuments constructed by Egyptians. They are tetrahedral in shape, i. They still have remained a mystery to the humankind.

Again, the shape of the pyramids is that of an equilateral triangle. 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. 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.

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 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.
