Question

8. If the sides of a triangle are 3 m, 4 m and 6 m long, determine whether the triangle is a
right angled triangle​

Answer 1

Answer:

using hypotenuse theorem

h² = b²+p²

6² = 3²+4²

36= 9 + 16

36 = 25

L.H.S. is not equal to R.H.S

so ,it is not a right angled triangle

Answer 2

Answer:

a= 3 m.

b = 4 m

c =6 m

$c ^{2} \: = a { ^{2} } + b^{2}$

$6 {}^{2} = 3 {}^{2} + 4 {}^{2}$

$36 = 9 + 16$

36 = 25

36 is not equal to 25

LHS is not equal to RHS

Hence it is now right angle triangle
