Frequently Asked Questions
What is the formula for the diagonal of a rectangle?
The diagonal equals the square root of the length squared plus the width squared, using the Pythagorean theorem.
What is the diagonal of an 8 by 6 rectangle?
An 8 by 6 rectangle has a diagonal of exactly 10 units.
Why does the diagonal use the Pythagorean theorem?
The diagonal, length, and width form a right triangle, since the length and width meet at a 90 degree corner, so the Pythagorean theorem applies directly.
