Q3. a) Use P.theorem to check which is a py.triplet 6cm, 8cm, 10cm b) 8 cm, 9cm, 13 cm bello Dia

(a) 6,8,10 

P. theorem if 

(hyp)² = (adj)²+(opp)²

6² +8² = 36 + 64 = 100 = 10²

6,8,10 are triplet (Pythagorien)

(b) 8cm 9cm, 13cm

 8² +9² = 64 + 81

145 $\ne$13²

145 $\ne$169

So 8,9,13 are not Pythagorien triplets
