Concept of similarity, congruent, condition for two Triangles are similar, condition for two polygons are similar, problems based on similarity of Triangles. 
1.If triangle ABC & PQR are similar, AB=6.5 cm,PQ=10.4 cm, and perimeter of triangle ABC=60 cm, find the perimeter of triangle PQR.

Similar Figures and Congruent Figures (in Hindi)

Criteria for similarity of Triangles 
1.AAA(Angle-Angle-Angle) 
2.SSS(Side-Side-Side)
3.AA(Angle-Angle)
4.SAS(Side-Angle-Side)
5.Similarity of right angled Triangles

Criteria for Similarity of Triangles (in Hindi)

1. Theorem: Basic proportionality theorem (BPT)
If a line draw parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.
2. Converse of BPT

Basic Proportionality Theorem (in Hindi)

Problems based on BPT and its converse 
Total 4 questions solved. 
1. If the length of sides given then prove that DE//BC
2.If the sides are parallel then find the value of x.

Problems based on BPT and its Converse (in Hindi)

Theorem: The ratio of the areas of two similar Triangles are equal to the  ratio of the squares of any two corresponding sides.
1. Problem based on this theorem.

Theorem: The ratio of the areas of two similar Triangles (in Hindi)

1. Problem based on equilateral triangle described on the side of a right angled triangle. 
2. If the areas of two similar Triangles are equal, prove that they are congruent. 
3. If the areas of two similar Triangles are 81cm^2 and 49cm^2 respectively, then find the ratio of their corresponding median.

mathematics is not only a sub.,
it is also a part of our life,
so every time of life do mathematics and learn mathematics

Ajay Kumar

We shall study about those figures which have tha same shape but not necessarily the same size. we shall discuss the similarity of traingles and apply this knowledge in giving a simple proof of Pythagoras theorem .
