Not enough information. If it's a right triangle, and the missing side is a leg, it could be 4 in. If the missing side is the hypotenuse, it would be the square root of 34.

Q: What is the length of the third side of a triangle when the first side is 5 in long and the second side is 3 in long?

That depends entirely on the size of the angles !

SAS Inequality Theorem the hinge theorem states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle.

A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.

If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.

An isosceles triangle is one in which two sides are of the same length, but the third is different.
