    This isn't a right triangle

    Step-by-step explanation:

    To see if this is a right triangle we use Pythagorean Theorem

    The formula is a^2+b^2=c^2

    We place the numbers in the formula:

    4^2+5^2=7^2

    4^2=16

    5^2=25

    7^2=49

    16+25+49

    41=49

    They are not equal which makes it not a right triangle.

    The triangle is not a right triangle

    Step-by-step 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
