Aldrine's Scribepost for Dec 14 2009


9. a) Calculate the areas of the three squares.

20cm= 400cm2
40cm= 1600cm2
50cm= 2500cm2

b) Is this triangle a right triangle? Explain.

No, because when you add 400+1600 the answer is 2000 its sopose to be 2500 to make the right triangle. 20 squared + 40 squared = 50 squared this is called phytagoream. If you add 400+1600 and the answer is 2500 you make a right triangle.
