If pq=21 cm and qr=5cm, then what are the possible lengths for pr so that line pq, line qr, and line pr can form a triangle? explain your reasoning

Let

x---------> the possible lengths for PR

we know that

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

so

case 1)

cm

case 2)

cm

case 3)

cm

so

therefore

the answer is

PR must be less than cm and must be more than cm
