Question 1. Equilateral triangles are drawn on the three sides of a right angled triangle. Show that the area of the triangle on the hypotenuse is equal to the sum of the areas of triangles on the other two sides. Question 2. Prove that the area of the equilateral triangle described on the side of a square is half the area of the equilateral triangles described on its diagonal. Question 3. Question 4.

Similar triangles class 10 exercise 8.3 solutions

Calculate the values of x and y. Prove that a line drawn through the mid-point of one side of a triangle parallel to another side bisects the third side Using basic proportionality theorem. Prove that a line joining the midpoints of any two sides of a triangle is parallel to the third side. Using converse of basic proportionality theorem. Show that BC QR. Show that.

Motivate If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side. An Introduction. As you carry on with the ratios of contemporary angles you will finally conclude that:. Students are advised to prepare all the chapters covered in the solution modules, which will eventually help them to gain a deeper knowledge of concepts. Simple situational problems. This chapter is the continuation of the previous chapter; here, the students will study the applications of trigonometry. Now, again, both 90 o — 3A and A — 26 o are acute angles. Area of sectors and segments of a circle. Chapter 2 - Polynomials. The line of sight is the line drawn from the eye of an observer to the point in the object viewed by the observer. Assuming that the above three conditions are known, how can we determine the height of the minar? Construction of a triangle similar to a given triangle. Practising NCERT textbook exercise solutions will surely help the students in their preparation for the examination. Students can also cross-check their answers while solving the textbook problems to get an idea about the other methods of answering the questions efficiently. Motivate If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.

Chapter 8 - Introduction to Trigonometry. Now, again, both 90 o — 3A and A — 26 o are acute angles. Area of sectors and segments of a circle. Chapter 1 - Real Numbers. NCERT books are best known for putting forth the concepts in a simple way for better understanding. The method of solving complex problems can be learnt easily. Students can also cross-check their answers while solving the textbook problems to get an idea about the other methods of answering the questions efficiently. Considering LHS,. Exercise 8. Assuming that the above three conditions are known, how can we determine the height of the minar? In Polynomials , the chapter begins with the definition of the degree of the polynomial, linear polynomial, quadratic polynomial and cubic polynomial. Trigonometry is the branch of mathematics dealing with relations between the sides and angles of triangles, along with the relevant functions that are related to the angles. The solutions to these questions present in the NCERT books can help students to clear their doubts quickly.
