Height of pyramids can also be find using. She pulls the string at the rate of 5 cm per second. Video — will be available soon. How far apart will be the two planes after hours? Hence, the ratio between the areas of these triangles will be equal to the square of the ratio between the sides of these triangles. A ladder 10 m long reaches a window 8 m above the ground. Sides of triangles are given below.
Therefore, the given triangle is a right-angled triangle. Therefore, the length of the hypotenuse of this triangle is 25 cm. Squaring the lengths of these sides, we will obtain 9, 64, and 36. State which pairs of triangles in Fig. If the areas of two similar triangles are equal, prove that they are congruent. Therefore, the triangle is a right triangle, right-angled at B.
The is the most efficient study material one can get for their Class 10 Board Exam preparation. Download for offline use as well as for offline use. Detailed answers of all the questions in Chapter 6 Maths Class 10 Triangles Exercise 6. The name of these concepts and theorems or rules are given below. The exercise is named as the optional exercise and provides extra questions, From all the topics covered in the chapter.
A triangle is a plane figure that has three sides and three angles. If you liked the video, please so that you can get more such interesting and useful study resources. Find each of its altitudes. Find the distance of the foot of the ladder from base of the wall. Therefore, the triangle is a right triangle, right-angled at B. At the same time, another aeroplane leaves the same airport and flies due west at a speed of 1,200 km per hour. Two poles of heights 6 m and 11 m stand on a plane ground.
Page No: 143 Exercise 6. Squaring the lengths of these sides, we will obtain 49, 576, and 625. Squaring the lengths of these sides, we will get 2500, 6400, and 10000. Assuming that her string from the tip of her rod to the fly is taut, how much string does she have out see Figure? The tip of her fishing rod is 1. Squaring the lengths of these sides, we will obtain 169, 144, and 24. Hence, it is not a right triangle iii Given that sides are 50 cm, 80 cm.
Give two different examples of pair of i Similar figures ii Non-similar figures Answer i Two twenty-rupee notes, Two two rupees coins. Squaring the lengths of these sides, we will get 169, 144, and 25. Page No: 138 Exercise 6. Squaring the lengths of these sides, we will get 49, 576, and 625.

These solutions can be helpful not only for the exam preparation but also in solving the homework and assignments. We know that the longest side of a right triangle is the hypotenuse. The chapter concludes by explaining the Pythagoras theorem and the ways to use it in solving problems. How far from the base of the pole should the stake be driven so that the wire will be taut? Page No: 150 Exercise 6. An aeroplane leaves an airport and flies due north at a speed of 1,000 km per hour. After you have studied lesson, you must be looking for answers of its questions. Therefore, the given triangle is not satisfying Pythagoras theorem.
Therefore, it is a right triangle. Squaring the lengths of these sides, we will get 9, 64, and 36. Prove that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding medians. If the distance between the feet of the poles is 12 m, find the distance between their tops. . In an equilateral triangle, prove that three times the square of one side is equal to four times the square of one of its altitudes.
Students often tend to get confused which theorem to use while solving one particular question. Using Basic proportionality theorem, prove that a line drawn through the mid-points of one side of a triangle parallel to another side bisects the third side. 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. Two triangles or any polygons of the same number of sides are similar, if i their corresponding angles are equal and ii their corresponding sides are in the same ratio or proportion. Therefore, the given triangle is not satisfying Pythagoras theorem. Ncert solution class 10 Maths includes text book solutions from Mathematics Book.
