Pythagoras Theorem
In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

00:03 Q6. ABC is an equilateral triangle of side 2a . Find each of its altitudes.
01:51 AAA similarity criterion
If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.
03:15 Pythagoras Theorem Application
In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
04:10 Result proved Altitude of equilateral triangle formula proof
Altitude of equilateral triangle IS SQRT(3)*(SIDE)/2.

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.
