Answer:

The right angled triangle

Answer 2

Answer:

It is the right-angled triangle.

Step-by-step explanation:

According to the Pythagorean theorem, $a^{2}+b^{2}=c^{2}$, which c is the longest side of the triangle.

So, $27^{2}+36^{2}=45^{2}$ if the triangle is right angle.

$LHS=27^{2} + 36^{2} = 2025$

$RHS=45^{2}=$$RHS=45^{2} = 2025$

∵LHS=RHS

∴It is a right-angled triangle.
