Answer:

It is not a Right Angled Triangle.

Explanation:

A right angled triangle is a triangle whose sides satisfy the following equality.

Lets say A triangle has sides a, b and c. Where c is the longest side.

Then,
a^(2) +b^(2) =c^(2)

Lets substitute the values to the above equation to see whether the triangle we are given satisfies the above equality,


4^(2) +15^(2) =
16+225=
241


18^(2) =324

Therefore,
4^(2) +15^(2) ≠[tex]18^{2}

So it is not a Right Angled Triangle.
