Important Questions of 10th Maths exercise 6.4
What is Area Theorem in class 10?
The ratio of areas of two similar triangles is equal to the square of the ratio of their corresponding sides. [This also known as Area Theorem. In this theorem, the ratio of area is equal to square of corresponding sides but ratio is also equal to the corresponding altitudes, median.]
How many theorems are there in chapter 6, which may be asked to prove?
There are four theorems in class 6 which are asked to prove:
1. BPT or Thales Theorem
2. Area Theorem
3. Pythagoras Theorem
4. Converse of Pythagoras Theorem
About 10 Maths Exercise 6.4
In Exercise 6.4, mainly we have to solve the questions based on ratio of area of similar triangles with their corresponding sides, perimeters, altitudes, medians, etc. In Exercise 6.3, we have learnt that if triangles are similar then their sides are proportional. Here, we have to relate it from area also.
Extra Questions on Similar Triangles
- In triangle ABC, If AD is the median, Show that AB² + AC² = 2(AD² + BD²)
- In triangle ABC, angle C is a right angle. Points P & Q lies on the sides CA & CB respectively. Prove that AQ² + BP² = AB² + PQ²
- If AD and PS are medians of angle ABC and angle PQR respectively where angle ABC ~ angle PQR, Prove that AB/PQ = AD/PS.
- In an equilateral angle ABC, AD is perpendicular to BC, Prove that 3AB² = 4AD².
- Prove that the sum of the square of the sides of a rhombus is equal to the sum of the squares of its diagonals.
