Answer:
Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).

Answer:
If a , b , and c units are the sides of a triangle then (a+b) > c > (a-b).
Thus , (9+7)cm > third side > (9–7) cm.
or. 16cm > third side > 2 cm
