Answer: Not a right-angled triangle

Explanation:

Given

The sides of a triangle are
7\ m, 8\ m, \text{and}\ 10\ m

For a right-angle triangle, it must satisfy the Pythagoras theorem


a^2+b^2=c^2

i.e. the square of the larger side must be equal to the sum of the square of the remaining two sides

Here,


\Rightarrow 7^2+8^2\ ?\ 10^2\\\Rightarrow 49+64\ ?\ 100\\\Rightarrow 113\\eq 100

Therefore, it is not a right-angle triangle
