Question

A triangle has sides with lengths of 55 kilometers,73 kilometers and 51 kilometers is it a right triangle

Answer 1

If/when we plug them into the formula and both sides are equal, then we know that the triangle is a right triangle.

We have the lengths of the three sides, so we can plug them into the formula:

55raise to the power2 + 73raise to the power2= 51 raise to thepower2

3025+5329= 2601

add left side

8354 =2601

No! That is not true! That means that this is NOT a right triangle.

Hope this helps!
