The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side the links of two sides of a triangle or 13 feet and 21 feet find the possible lengths of the third side
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. Note: This rule must be satisfied for all 3 conditions of the sides.
