1Ruel, Geralyn, Reymond and Shiela were given a 24-inch piece of stick each. They were instructed to create a triangle. Each cut the stick in their own chosen lengths as follows: Ruel-8 in, 8 in, 8 in; Geralyn- 5 in, 7 in, 12 in; Reymond-9 in, 7 in, 8 in; and Shiela-6 in, 8 in, 10 in. Who among them could NOT be able to form a triangle?

• Ruel

• Geralyn

• Sheila

• Reymond
