Under this topic, questions related to the linear equation (ax + by + c = 0) in two variables x and y are asked. For each value of x, we get the corresponding values of y, in which the pair (x, y) is obtained by coordinating the points obtained by matching the points obtained by following the rectangle of their places. Thus, the diagram of the linear representation equation (ax + by + c = 0) is obtained.

### Triangle And Its Various Centre:-

Under this topic, questions related to the type of triangle and its various centers are asked. To solve the questions based on the triangle, it is also necessary to know the various concepts of the triangle with its various types and its main centers. These types of questions can be solved quickly by some specific theorems or outcomes.

### Congruence And Symmetry Of Triangles:-

Under this topic, questions related to congruence and symmetry of the triangle are asked. These questions are mainly based on the comparative study of two plane triangles. While solving these types of questions, it is also necessary to know about specific theorems or outcomes with the concept of congruence and symmetry of the triangle.
