Question

The sides of a tringle are 15cm 36cm and 39cm verify that it is right angle trigle

Answer 1

39^2 = 15^2 + 36^2

if it holds then it is a right angled triangle........

Answer 2

let triangle ABC,
a
AB equal to 15 CM BC equal to 36 cm and AC
equal to 39 CM
AC is hypotenuse,
by coveese of Pythagoras theorem
hypotenuse^2=one side square + other side^2 a b square + BC square
15*15+36*36=225+1296=1521
AC square is also 1521.
hey triangle ABC is a right angled Triangle by Converse of Pythagoras theorem
