Answer:

Congruent Triangles are an important part of our everyday world,especially for reinforcing many structures.Two triangles are congruent if they are completely identical.This means that the matching sides must be the same length and the matching angles must be the same size.

Answer:

Triangle is the most stable figure it of the world.

Triangles are indeed an important part of our daily life whether we notice them or not. From the basis concepts to the complex calculations triangles have already dominated the entire area in which they are considered a significant aspect. Triangles feature in a number of aspects in our day to day lives including engineering, mathematics, architecture, astronomy, construction, physics, navigation, miscellaneous, etc.

Mathematics :

Triangles play a very important role in the areas of mathematics. The use of triangles have made it easy to determine the unknown quantities in geometry, trigonometry, etc.

The major uses of triangles include:

Almost all the 2 dimensional geometric shapes are made of series of triangles arranged in certain manner except the circle.

Trigonometry itself means the “measurement of triangles” , which means it is usually easy to determine the dimensions of the triangular shape using the Pythagoras’ theorem and the function like sine and cosine.

Concepts of triangles using trigonometry to find distance and height

Well established theorem are mainly based on triangles like Pythagoras'theorem and many more concepts of Euclid geometry are too based on triangles like the right angled triangle that provides the computational ease with easy understanding.
