# Exploring Pythagoras' Theorem

Investigate Pythagoras' Theorem by changing the size of the red triangle using the blue circles. You can also rotate the square on the hypotenuse (longest side) labeled C using the black dot in the corner.

Find the Area of each square sides of the right angle triangle is a=4 b=3 c=5

What do you notice about the area of these three squares? Check and write a rule for what do you explore

Drag the blue point to set the a=3 b=4 Repeat the same step by setting anther a and b WHAT DO YOU NOTICE ? WRITE THE RULE CAN WE USE THIS RULE FOR ANY RIGHT ANGLE TRIANGLE ?
