Teacher : Nuri Martini, S.Si, M.Pd


Learning Objective 
Students will be able to do investigation of Pythagoras' Theorem from variety methods

A right angled triangle is a triangle which has a right angle as one of its angles. The side opposite the right angle is called the hypotenuse, and is the longest side of the triangle. The other two sides are called the leg of the triangle.
Around 500 BC, the Greek mathematician Pythagoras discovered a rule which connects the lengths of the sides of right angled triangles.
In geometric form, Pythagoras' theorem states that :
In any right angled triangle, the area of the square on the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
A theorem is a fact that has been proven to be true.

Student's Activity
1. Students do investigation of proofing Pythagoras' theorems with the following steps
a. Research about methods of proofing Pythagoras' theorem and choose minimum 4 methods to be investigated by students
b. Learning the method choose and try to make a model of it use colour paper with random size then stick on A4 paper.
c. Showing all the proofing on written report

2. Format of written report
    a. Cover title
    b. Introduction (Describe your knowledge about : Who is Pythagoras? What is the Pythagoras' theorem, When do you use the Pythagoras' theorem)
    c. What to do (Brief Description of each method that you choose include with algebraic explanation and picture/model of the methods)
    d. Conclusion
    e. Attachment (All models of each methods need to be stick on A4 paper separately for each methods)
    f. Resources
