similarity practice set -1.2 Q.no. 2,3,4


Definition:

Do figures similar hote hain agar unke corresponding angles equal hote hain aur corresponding sides proportional hote hain.


---

Important Points of Similarity:

1. Corresponding Angles Equal (AA condition)
Agar do triangles ke do angles same hote hain, to teesra angle automatically same hota hai → aur triangles similar hote hain.


2. Corresponding Sides Proportional (SSS condition)
Agar do triangles ke sides proportional hain (ratio same hai), to wo triangles similar hain.


3. SAS Condition
Agar ek angle equal ho aur us angle ke dono sides proportional ho, to triangles similar hote hain.

Example:

Ek chhoti aur badi triangle dono right-angled hain aur ek angle 30° hai. Dono ka shape same hai → similar triangles.

Rectangle aur ek bada rectangle (same ratio of length & breadth) bhi similar hote hain.

👉 Geometry me Similarity ka use mainly triangles me hota hai – jisme hum unknown side nikalne ke liye ratio ka use karte hain.
