00:03 Q11. An aeroplane leaves an airport and flies due north at a speed of 1000 km per hour. At the same time, another aeroplane leaves the same airport and flies due west at a speed of 1200 km per hour. How far apart will be the two planes after 1 and 1/2 hours?

03:45 Pythagoras theorem

05:24 Worked out Word problems on Pythagoras Theorem.

Q12. Two poles of heights 6 m and 11 m stand on a plane ground. If the distance between the feet of the poles is 12 m, find the distance between their tops.

07:49 Pythagoras Rule

08:52 Q13. D and E are points on the sides CA and CB respectively of a triangle ABC right angled at C. Prove that AE^2 + BD^2 = AB^2 +DE^2.

10:19 Pythagoras Theorem

13:04 Q14. The perpendicular from A on side BC of a? ABC intersects BC at D such that DB = 3 CD(see Fig. 6.55). Prove that 2AB2 =2 AC2 + BC2.

14:43 Pythagoras Theorem

15:54 Deductions to simplify and prove the results

17:22 Q15. In an equilateral triangle ABC, D is a point on side BC such that BD = 13 BC. Prove that 9 AD2 = 7 AB2.

18:39 Consider two triangles & apply Pythagoras Theorem

20:15 AA similarity criterion

If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.

20:35 conditions for two triangles to be similar

Two triangles are similar, if (i) their corresponding angles are equal and (ii) their corresponding sides are in the same ratio (or proportion)

26:00 Q16. In an equilateral triangle, prove that three times the square of one side is equal to fourtimes the square of one of its altitudes.

27:35 AA similarity rule

29:01 Pythagoras Theorem.

In this video, we learn how to apply Pythagoras Rule to solve Problems on right-triangles.Use parallel lines concept and triangle similarity theorems to prove problems on solving similar triangles.Many Word problems are solved using Pythagoras Theorem.
