Question #926c8

Answer 1

No.

Explanation:

First, remember the Pythagorean Theorem: `a^2+b^2=c^2` where `c` is the hypotenuse, or the longest side of the right triangle, and `a` and `b` are the other two sides

`"Pythagorean Theorem only works on right triangles"`

Therefore, we can try our `4-5-7` triangle.

We ask ourselves: Is `4^2+5^2=7^2`? Let's try it out.

=>`16+25?49`

=>`41!=49`

Therefore, our triangle is not a right triangle.
