### Demvry's Pythagoras

H.W
Page 91-94

5) a)

b)402=1600
752=5625
852=7225

c)a2+b2=c2
402+752=852
(40x40)+(75x75)=(85x85)
1600
2+56252=72252
7225mm2=7225mm2

10)

a2+b2=c2
1202+1602=2002
(120x120)+(160x160)=(200x200)
14400
2+256002=400002
40000mm2=40000mm2

Yes,I think this is a right triangle since a
2 plus b2 equals c2.
(144002+256002=400002)

15)

a2+b2=c2
6
2+82=102
(6x6)+(8x8)=(10x10)
362+642=1002
100cm2=100cm2

I think this is a right triangle since 362 plus 642 equals 1002

9) I couldn't think of an answer so I wasn't able to do this. So sorry!
102+152=?2
