Description

**NCERT Solutions for Class 10 Maths** **Chapter 6 Triangles** is a self-paced course is designed to help CBSE/ NCERT students to understand concepts and application through videos. You can view these classes as many times as you want to clear the concepts. The comprehensive nature of this course will help you be prepared for CBSE board exams, competitive exams and in engineering entrance examinations.

**Key Features:**

- Each question is explained with concepts.
- Notes, Formulas, Definitions, Key points are included in the videos, while explaining each question.
- While explaining each solutions, we have added small anecdotes, pictures which you would find interesting.

**How to get most from this video course:**

- Schedule time and watch videos.
- Take Notes as we solve each exercise.
- We recommend you solve each question on your own before going through video explanation.
- Practice NCERT solutions every day.
- Teach it to someone (anyone).

**In this course we learn the following points **

- Two figures having the same shape but not necessarily the same size are called similar
- figures.
- All the congruent figures are similar but the converse is not true.
- Two polygons of the same number of sides are similar, if (i) their corresponding anglesare equal and (ii) their corresponding sides are in the same ratio (i.e., proportion).
- If a line is drawn parallel to one side of a triangle to intersect the other two sides indistinct points, then the other two sides are divided in the same ratio.
- If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side.
- If in two triangles, corresponding angles are equal, then their corresponding sides are inthe same ratio and hence the two triangles are similar (AAA similarity criterion).
- If in two triangles, two angles of one triangle are respectively equal to the two angles of the other triangle, then the two triangles are similar (AA similarity criterion).
- If in two triangles, corresponding sides are in the same ratio, then their corresponding angles are equal and hence the triangles are similar (SSS similarity criterion).
- If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in the same ratio (proportional), then the triangles are similar(SAS similarity criterion).
- The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.
- If a perpendicular is drawn from the vertex of the right angle of a right triangle to thehypotenuse, then the triangles on both sides of the perpendicular are similar to thewhole triangle and also to each other.
- In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (Pythagoras Theorem).
- If in a triangle, square of one side is equal to the sum of the squares of the other twosides, then the angle opposite the first side is a right angle.
