A triangle has sides with lengths of 4 meters, 5 meters, and 7 meters. Is it a right triangle

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
