Question

If the sides of a triangle are 3 cm, 4 cm and 6 cm long, determine whether the triangle
is a right-angled triangle.
hlou Determine which of them are right.​

Answer 1

Step-by-step explanation:

3^2+4^2=25=5^2

so a triangle with sides 3,4,6 is not a right triangle

Answer 2

Answer:

no it is not a right angled triangle

Step-by-step explanation:

by pythagoras theorem, if it was to be a right angled triangle,

sum of squares of two of its sides must be equal to the square of hypotenuse.

but,

3²+4²≠6²

∴this is not a right angled triangle
