Let AC = 29.9 cm base of an isosceles triangle, AB = BC = 15 cm its lateral sides.
A triangle can be built if the sum of any two of its sides is greater than the length of the third side.
Let’s check this condition.
AB + BC = 15 + 15 = 30.
30> 29.9.
AC + AB = 29.9 + 15 = 44.9.
44.9> 15.
AC + BC = 29.9 + 15 = 44.9.
44.9> 15.
Answer: You can build a triangle.
