These are very good for exam preparation. How far from the base of the pole should the stake be driven so that the wire will be taut? Prove that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding medians. Prove that the sum of the squares of the sides of rhombus is equal to the sum of the squares of its diagonals. Students have to cover each and every important topic of maths class 6. Prove that the area of an equilateral triangle described on one side of a square is equal to half the area of the equilateral triangle described on one of its diagonals. Concepts based on angle, polygon, triangle, quadrilateral, regular polygon, circle, radius and centre of a circle. The feedback form is so simplified that it would not waste your time, just type your name and give your suggestions.

All congruent figures are similar but the similar figures need not be congruent. The chapter deals with an introduction to Arithmetic Progression with the help of simple daily life examples and gradually deals with the topic and its complexities. Two poles of heights 6 m and 11 m stand on a plane ground.
Number of — no line of symmetry, one line of symmetry, two lines of symmetry, three lines of symmetry and so on. Find the age of the father. He recognized the need for conditions to be placed upon unknown variables in order to find a solution. A ladder 10 m long reaches a window 8 m above the ground. In ganit 10, prashnavali 3. Similarity of geometric figures is an important concept of Euclidean geometry. All the concepts and theorems are explained in a simple language with examples and a large number of exercise questions to develop confidence within the students so that they can perform best during the examination.
Moreover, some important or difficult questions are provided with multiple approaches to the answer to provide the students with an option to choose the best approach for them. Find the number of lines in the wheel. Hence, it is right angled triangle. Complete and a brief description about triangles, , theorems and the facts related to this chapter are given below. He can row 12 km downstream and 12 km upstream in 4 hours. The distance of the image of a point or object from the line of symmetry mirror is the same as that of the point from that line of symmetry.
Since the diagonals of a rhombus bisect each other at right angles. If the digits of the number differ by 3, find the number. One car starts from A and another from B at the same time. A guy wire attached to a vertical pole of height 18 m is 24 m long and has a stake attached to the other end. Page No: 128 Exercise 6.
Determine which of them are right triangles? Sides of two similar triangles are in the ratio 4 : 9. If a pair of linear equations is given as the following form, then the following situations can arise: The condition for the pair of linear equations is consistent, is as follows: The condition for the pair of linear equations is inconsistent, is as follows: The condition for the pair of linear equations is dependent and consistent, is as follows: Historical Facts! Line symmetry is closely related to mirror reflection. Therefore by Pythagoras theorem, we have, ………. In this chapter, students shall discuss patterns in which succeeding terms are obtained by adding a fixed number to the preceding terms. A guy wire attached to a vertical pole of height 18 m is 24 m long and has a stake attached to the other hand. To keep the wire taut, let it be fixed to a stake at A. A ladder 10 m long reaches a window 8 m above the ground.
Lucid language, examples, pictorial representation and highlighting of important terms make this chapter interactive and interesting. Take hints from these and make your effort to solve the questions. Sides of triangles are given below. Register for our free webinar class with best mathematics tutor in India. Unsolved problems provide hints and use pictures to make the students understand the questions and solve them easily. Perfect number — a number whose sum of all factors is equal to two times the number. Find the height of the tower.
After 30 years, sum of the ages of the children will be twice the age of the father. Length of the hypotenuse of this triangle is 13 cm. What is the inspiration behind this? Gauss brought his theory to solve systems of equations proving to be the most effective basis for solving unknowns. The topics and sub-topics in Chapter 5 Arithmetic Progression are given below, Ex 5. A vertical pole of length 6 m casts a shadow 4 m long on the ground and at the same time a tower casts a shadow 28 m long. Find the number of notes of each denomination.
