Question

How to use pythogarous method.
PQR IS A TRIANGLE IF PQ IS 10 CM. And PR IS 24 CM. And P IS A RIGHT ANGLE THEN WHAT IS THE LENGTH OF QR.

Answer 1

QR ^2 = PQ^2 + PR ^2 QR^2 = 10^2 + 24^2 QR 2 = 100 + 576 QR^2 = 676 QR = Root 676

Answer 2

Pythagoras theorem = a² + b² = c²

Where,
a and b are legs of the triangle
c is the hypotenuse


In ∆PQR,
PQ² + PR² = QR²
10² + 24² = QR²
QR = √676
QR = 26 cm
