🌟 Description for Exercise 7.2 (Q-5, 6, 7, 8)

In this part of the exercise, you practise the congruency of triangles using rules like SAS (Side-Angle-Side), ASA (Angle-Side-Angle), and RHS (Right angle-Hypotenuse-Side).
The questions help you understand how corresponding parts of congruent triangles are equal (CPCT) and how to use these properties to prove triangles congruent, find unknown angles, or show equality of sides.

🔸 Question 5:

You compare two triangles with given angles and a side between them. You apply the ASA rule to prove they are congruent and then use CPCT to get required equalities.

🔸 Question 6:

You work with triangles placed in a geometric figure and prove them congruent using SAS or ASA, depending on given information. Then you conclude the equality of sides or angles.

🔸 Question 7:

A right triangle–based question where you apply RHS congruence rule (Right angle, Hypotenuse, Side). After proving the triangles congruent, you use CPCT to find the required relation.

🔸 Question 8:

You use the concept of common sides and given angles to prove triangles congruent, again using ASA or SAS, and then derive equal angles from the congruency.
