Question

the sides of a triangle measure 15 cm,36cm and 39 cm.Show that it is a right angled triangle

Answer 1

HEY MISS.!!

HERE'S THE ANSWER..

_______________________________

♠️ We know in right angled triangle we can apply Pythagoras , in this case we have to prove that it is a right angled triangle, so we'll put the values of side and check that is follows Pythagoras or not .

▶️ According to Pythagoras theorem

✔️( Hypo. )^2 = ( B )^2 + ( P )^2

⏺️Here 39 is the largest side so we'll take is as hypo.

=> ( 39 )^2 = ( 36 )^2 + ( 15 )^2

=> 1521 = 1296 + 225

=> 1521 = 1521

♠️ So it is satisfying Pythagoras , Hence it is a right angled triangle..

HOPE HELPED..

JAI HIND..

Answer 2

h^2 = b^2 + p^3

39^2 + 36^2 + 15^2

1521 = 1296 + 225

1521 = 1521

hence proved
