Yes check: the sum of the two length sides > the 3rd length side the difference of the two length sides < the 3rd length side
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
Is this a right triangle or what? You need more information.
Perimeter: 5+10+length of its 3rd side
Not enough information has been given to find the measure of the 3rd side of the triangle ABC but if it is in the form of an isosceles triangle then the 3rd side would work out as 6 units.

Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
The third side can have any value in the range (2 cm, 16 cm).
