NCERT Solutions Class 10 Maths Chapter 6, Triangle of Class 10 Maths NCERT solutions of Chapter 6 Triangles part of Geometry which constitutes 15 marks of the total marks of 80. NCERT solutions of Chapter 6 Triangles Based on the CBSE Class 10 examination prospectus, this chapter 6 has the second-most elevated weightage. Consequently, having a clear understanding of the ideas, theorems, and problem-solving techniques, in this section it is compulsory to score well in the Board assessment of class 10 maths.

From your previous classes, you know about triangles and a considerable lot of their properties. In Class 9, you studied the congruency of the triangles in detail. In this part, we will consider those triangles which have a similar shape but not really a similar size. Two triangles having a similar shape (and not really a similar size) are called similar triangles. In chapter 6 of class 10 maths, we will study the similarity of triangles and the application of this property in giving a basic verification of the Pythagoras Theorem learned before.

### NCERT Solutions for Class 10 Maths of Chapter 6 Triangles

In Class 9, you have seen that all circles with similar radii are congruent, all squares with a similar side length are congruent and all equilateral triangles with a similar side length are congruent. The chapter clarifies the similarity of triangles by playing out the applicable action. Similar triangles are two triangles having a similar shape yet not really a similar size.

The topic recalls triangles and their similarities. Two triangles are similar if (i) their corresponding angles are equal and (ii) their corresponding sides are in the same ratio (or proportion). It explains Basic Proportionality Theorem and different theorems are discussed in performing various activities.

Basic Proportionality Theorem- If a line is drawn parallel to one of the sides of a triangle such that it intersects two sides then it divides the other two sides of the triangle in the same ratio.

In the previous section, we stated that two triangles are similar (i) their corresponding angles are equal and (ii) their corresponding sides are in the same ratio (or proportion). The topic discusses the criteria for the similarity of triangles referring to the topics we have studied in earlier classes. It also contains different theorems explained with proper examples.

AAA rule-If in two triangles three corresponding angles are the same,then both of triangles are similar to each other

AA rule – If in two triangles two corresponding angles are the same,then both of triangles are similar to each other.

SAS rule – If in two triangles two corresponding sides are in proportion and the angles subtended by them are also equal then triangles are similar to each other.

SSS rule- If all corresponding sides of two triangles in proportion then both of the triangles are similar to each other.

If in two triangles ΔABC and ΔDEF

AB/DE =BC/EF =AC/DF

then ABC ∼DEF

∠B = ∠E

ΔABC ∼ ΔDEF (SAS rule)

SSS rule- If all corresponding sides of two triangles in proportion then both of the triangles are similar to each other.

AB/DE =BC/EF =AC/DF

ΔABC ∼ ΔDEF (SSS rule)

#### NCERT Solutions for Class 10 Maths of Chapter 6 Triangles

You have learned that in two similar triangles, the ratio of their corresponding sides is the same. The topic Areas of Similar Triangles consists of a theorem and relatable examples to prove the theorem.

The ratio of the areas of two similar triangles is equal to the ratio of the square of their corresponding sides.

You are already familiar with the Pythagoras Theorem from your earlier classes. You have also seen proof of this theorem in Class 9. Now, we shall prove this theorem using the concept of the similarity of triangles. Hence, the theorem is verified through some activities and made use of it while solving certain problems.

Hypotenuse² = Perpendicular² + Base²
