True, the three sides will form exactly one unique triangle.
What is a triangle?
A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.
- let the first length = a
- let the second length = b
- let the third length = k
(b - a) < k < (b + a)
(6.3 cm - 5.2 cm) < k (6.3 cm + 5.2 cm)
1.1 cm < k < 11.5 cm
The third length = 10.5 cm which is greater than 1.1 cm and less than 11.5 cm.
Thus, the three sides will form exactly one unique triangle.
