Question 530667
First, an isosceles(sp.) triangle has at least two equal sides.
So if one side measures 7, then:
A. 7 and 14 will not work because the longest side (14) is exactly equal to the sum of the other two sides (7+7) and this does not form a triangle.
B. 15 and 7 will not work for the same reason stated in A.
C. 15 and 15 will work because you will have two equal sides (15 and 15) and the third side (7) will connect to form a triangle.
D. 3 and 3 will not work for the same reason stated in A.
