Pythagoras Theorem

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

Converse of Pythagoras Theorem

In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle.

00:04 Q4. ABC is an isosceles triangle right angled at C. Prove that AB^2 = 2AC^2.

00:49 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.

01:45 Q5. ABC is an isosceles triangle with AC = BC. If AB^2 = 2 AC^2, prove that ABC is a right triangle.

03:12 Use Converse of Pythagoras Theorem

In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle.

03:45 Q6. ABC is an equilateral triangle of side 2a . Find each of its altitudes.

05:35 AAA similarity criterion

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

07:08 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.

07:58 Result proved Altitude of equilateral triangle formula proof

Altitude of equilateral triangle IS SQRT(3)*(SIDE)/2.
