Nilai yang paling besar merupakan sisi miring(I) 8, 12, 14
14² = 12² + 8²
196 = 144 + 64
196 < 108 (segitiga lancip)
(II) 11,12,16
16² = 12² + 11²
256= 144 + 121
256< 265 (segitiga lancip)
(III) 12,15,20
20² = 15² + 12²
400 = 225 + 144
400 > 369 ( SEGITIGA TUMPUL)
(IV) 15,20,30
30² = 20² + 15²
900 = 400 + 225
