Question

in∆pqr, anglepqr=90° and the length of the hypotenuse pr is 13cm find pq square +qr square

Answer 1

Answer:

169cm

Step-by-step explanation:

since pqr is 90°, This triangle is a right angled triangle and we can use Pythagoras Theorem.

which states, Hypotenuse² = sum of the squares of the other sides.

given, Hypotenuse = 13cm

Therefore,

13² = pq² + qr² = 169cm
