PROVE PYTHAGOREAN THEOREM
Step 1Cut equally your origami paper into 2 rectangles
PROVE Pythagorean Theorem Step 2Cut the rectangle into 2 right angle triangles
PROVE Pythagorean TheoremNow, you have 4 right angle triangles. We will
form the triangle as follow!
a
b c
c
cc
ca - b
PROVE Pythagorean TheoremArea of square =
4 ( area of triangle ) + area of small square
= 4 +
= 2bc + a2 – 2ab + b2
c2 = a2 + b2
c
cc
ca - b
PYTHAGOREAN THEOREM
•c2 = a2 + b2 •a2 = c2 – b2
•b2 = c2 – a2
a
bc
