Hiiii Associates M Akshay gupta. It isn't probable to operate them upon violent waters. I'm contemptible for a nuisance .

Fill in the blanks by using the correct word given in brackets. Give two different examples of pairs of i similar figures. State whether the following quadrilaterals are similar or not.

In the given figure i and ii , DE BC. Find EC in i and AD in ii. Show that EF QR. Show that BC QR. Using B. Recall that your have proved it in class IX Solution:. Using converse of B. Recall that your have done it in class IX Solution:. State which pairs of triangles in the given figures are similar. Write the similarity criterion used by you for answering the question and also write the pairs of similar triangles in the symbolic form :. Prove that: Solution:.

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 height of the tower. If the areas of two similar triangles are equal, prove that they are congruent. 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 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. Areas of these triangles are in the ratio a 2 : 3 b 4 : 9 c 81 : 16 d 16 : Sides of triangles are given below. Thales of Miletus � BC, Greece was the first known philosopher and mathematician.

He is credited with the first use of deductive reasoning in geometry. He discovered many propositions in geometry. He is believed to have found the heights of the pyramids in Egypt, using shadows and principle of similar triangles. Height of pyramids can also be find using applications of trigonometry.

According to Galileo Galilei, the universe cannot be read until we have learnt the language in which it is written. It is written in mathematical language and the letters are triangles, circles and other geometrical figures, without which it is humanly impossible to comprehend a single word.

Determine this is a right triangles. In case of a right triangle, write the length of its hypotenuse. Sides of triangle: 7 cm, 24 cm and 25 cm. Squaring these sides, we get 49, and We know that the hypotenuses is the longest side in right angled triangle.

Hence, its length is 25 cm. ABC is an isosceles triangle right angled at C. Once the students are made familiar with the concept of similarity, they are then introduced to the criteria under which two or more triangles are deemed similar. A thorough understanding of this topic will allow students to form the Ch 2 Maths Class 10 Green Board Youtube base for solving complex problems in higher mathematics.

This section outlines and explains the criteria for the similarity of triangles. The basic criteria for two triangles to be called similar include: if their corresponding angles are equal and if the corresponding sides of the triangles are in the same ratio or proportion.

Students will be able to visualise the theorems as they are illustrated with the help of proper examples. Students can understand the formula and learn the process for finding the surface area of similar triangles in this section. Students have already learnt the theorem and its proof in Class 9.

In this section, students will learn how to prove this theorem by employing the concept of similarity of Ch 2 Maths Class 10 Green Board Level triangles. The summary comprises all the topics that you have studied in the chapter. Going through the summary will allow you to recollect all that you have learnt in the chapter including the important concepts, theorems, etc. The list of exercise in the Maths Class 10 Chapter 6 has been provided below:. Students using these solutions to prepare for the exam benefit due to the following reasons:.
