Understanding Similarity: Class 10 Maths Chapter 6 Concepts
Before Starting the chapters, Lets us discuss about some important topic which is used in this Chapter. Lets us discuss about Congruency of a triangle and Similat Triangle.
The 5 Rules of Triangle Congruence
SSS (Side-Side-Side): All three sides of one triangle are equal to the three sides of another triangle.
SAS (Side-Angle-Side): Two sides and the included angle (the angle directly between them) of one triangle equal those of another.
ASA (Angle-Side-Angle): Two angles and the included side (the side between the two angles) of one triangle equal those of another.
AAS (Angle-Angle-Side): Two angles and a non-included side of one triangle are equal to the corresponding parts of another.
RHS (Right angle-Hypotenuse-Side): In two right-angled triangles, the hypotenuse and one matching side are equal.
Similar Triangles…
Two triangles are similar if they have the exact same shape but can be different sizes. This means their corresponding angles are identical, and their corresponding side lengths are proportional.
To prove two triangles are similar, you only need to satisfy one of the following three fundamental geometric rules:
1. AA (Angle-Angle) Rule
The Rule: If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.
2. SAS (Side-Angle-Side) Similarity Rule
The Rule: If two pairs of sides are proportional, and the included angle (the angle directly between those two sides) is equal in both triangles.
3. SSS (Side-Side-Side) Similarity Rule
The Rule: If all three pairs of corresponding sides are proportional, the triangles are similar.

📖 Frequently Asked Questions (FAQs on SEBA Class 10 Triangles)
Q1: Are all congruent figures similar to each other? Ans: Yes, all congruent figures are similar, but all similar figures are not necessarily congruent.
Q2: What is the main condition for two polygons to be similar under the SEBA syllabus? Ans: Their corresponding angles must be equal, and their corresponding sides must be in the same ratio (proportional).
