Question
The sides of certain triangles are given below. Determine which of them are right triangles. $a =16 cm, b =3.8 cm$ and $c =4 cm$.
✓
Answer
Sides of the triangle are $a=1.6 cm, b =3.8 cm, c =4 cm$ $\left(\right.$ Longest side) ${ }^2=(4)^2=16$
Sum of squares of shorter two sides $+(1.6)^2+(3.8)^2=2.56+14.44=17.00$
$16 \neq 17$
It is not a right triangle.
