If you want you can do this or search in google for different methods OBJECTIVE: -

To verify the Pythagoras theorem by method of Paper Folding, Reducing and Pasting

THEORY: --

Pythagoras theorem: - That states that in a correct angled triangular, the square of the largest side (Hypotenuse) is equal to the amount of the pieces of the other two sides(Perpendicular as well as the base).

PRE-REQUISITE KNOWLEDGE: -

• Area of a Rectangular

• Building of Seite an seite lines and Perpendicular bisectors • Development of a Right triangle

COMPONENTS REQUIRED: --

Coloured Newspaper, A pair of Scissors, Geometry field, Sketch Pens, Fevicol

TREATMENT: -

1) Cut out the right angled triangle ABC, with sides AC=8cm, AB=10cm, BC=6cm. 2) Lower 3 pieces of proportions 6cm back button 6cm, 8cm x 8cm and 10cm x 10cm. 3) Place these potager on the sides of the triangular ABC related to the sides of the sq. 4) Today join the the gauche of the sq placed on the perpendicular and also the base, claim perpendicular. 5) Throught the intersection point of the diagonals draw a line seite an seite to the foundation of the Hypotenuse AB of triangle DASAR. 6) Right now draw perpendicular bisector with the line section drawn inside square...
