Question

A triangle has sides with lengths of 4 meters 5 meters and 7 meters
is it a right triangle

Answer 1

The triangle is not a right triangle

Explanation:

The sum of the squares of the side lengths do not equal the square of the hypotenuse:

4^2+5^2=7^2

16+25=49

41=49

41 does not equal 49, so this confirms my answer is true
