Question

Tell whether the triangle with the given side lengths is a right triangle. Justify your answer.

81 m, 91 m, 98 m

Answer 1

No, it isn't.

Explanation:

The Pythagorean theorem doesn't work here.

Answer 2

The triangle specified is not a right triangle.

Explanation:

The angles of a right triangle will always add up to 180 degrees. The angles specified add up to 270 degrees.

There will also always be a 90 degree angle which makes up the right angle.

Since there will always be a 90 degree angle, the other angles will have to add up to 90.
