**2. Following concepts of chapter 13 of ICSE Class 10, what is a centroid of a triangle? Which formula is used for finding it?**

The centroid of a triangle is defined as the point of intersection where the medians of the triangle intersect each other.

The centroid of a triangle describes the ratio of the median. The ratio of every median is 2:1.

Consider a triangle having vertices A, B, and C. The vertices of the triangle are defined as A (x1, y1), B(x2, y2), and Z (x3, y3)

The centroid of a triangle = (x1 + x2 + x3/ 3, y1 + y2 + y3/ 3).

**3. How to solve the questions in which the ratio is not given for ICSE Maths class 10 chapter 13?**

It is suggested that the ratio should be taken as k:1 in those questions in which the ratio is not mentioned. In this way, two unknown ratios m1 and m2 change to known ratio k:1. Without this ratio, the section formula becomes, x = kx2 + x1/ k + 1 and y = ky2 + y1/ k + 1

By putting the value of x and y, two equations will be obtained. By solving those two equations, the actual value of the ratio will be obtained.

**4. How many exercises are there in Chapter 13 Section and Midpoint Formula of the ICSE Class 10 Mathematics?**

Chapter 13 Section and Midpoint Formula of the ICSE Class 10thMathematics comprises three exercises. The number of questions in these exercises is as follows:

Exercise 13A –26 questions

Exercise 13B –18 questions

Exercise 13C – 22 questions

Students have to solve each question of this chapter to make a strong grip over the concepts. They can get the solutions to these questions on the internet or buy reference books from the markets. By practicing these questions, they will get to know how to attempt questions in the proper format of the main examination paper.

**5. Following the concepts of class 10 ICSE Maths, solve the following:**

**The coordinates of the vertices of triangle ABC are given as A(3,1), B(y, 4), and C(1,x). The centroid of the triangle is G(3,4). Find the unknown variables x and y.**

Given that A(3,1), B(y, 4) and C(1,x) are vertices of the triangle ABC.

The centroid of a triangle = (x1 + x2 + x3/ 3) = (y1 + y2 + y3/ 3)

Also, centroid given in the question = G(3,4)

Therefore, 3 = (3 + y + 1/ 3) = (4 + y/ 3)

9 = 4 + y

5 = y

4 = (1 + 4 + x/ 3) = (5 + x/ 3)

12 = 5 + x

7 = x
