Theory:

Two figures are said to be congruent if they have the same size and same shape. Two figures are similar if they have the same shape but need not of the same size.
In this chapter, we will learn the concept of similar figures and discuss the similarity of triangles and apply this concept by providing proof for the Pythagorean thorem.
 
Did you ever wonder how the height of the pyramid in Egypt is measured?

Or the distance of Saturn from the Sun have been found out?

Their heights and distances are determined using the idea of indirect measurements, which is based
on the principle of similarity of figures.
 
In this chapter, we will learn about the concept of similar figures and how they are applied in real life.
