(A)squared plus (B) squared = (c)squared
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
3 inches, an equilateral triangle has equal side lengths and angle measures
There is not enough information to calculate the two missing sides.
Doesn't it depend on what type of triangle it is? And which sides you are measuring? And which side it's laying on?

An isosceles triangle has two sides with equal measures. The third side can be any length.
3 inches, an equilateral triangle has equal side lengths and angle measures
It is an isosceles triangle if 2 sides measure 25 feet and the other side measures 10 feet
There is not enough information to calculate the two missing sides.

In general the 2 smaller sides of a triangle when added together must be greater than its biggest side.
If it is and equilateral triangle, the perimeter is 12, otherwise it is impossible to figure out without any angle measurements or other sides lengths
This would be an isosceles triangle.
An Isosceles Triangle
If you mean sides of 10, 12 and 16 then yes a triangle be constructed because the sum of its 2 smaller sides is greater than its longest side.
