In a square the length of both the diagonals are the same. Diagonal a² a² 2 a² which simplifies to. Using the diagonal and side length formula.
We can use Pythagoras Theorem to find the length of the diagonal if we know the width and height of the rectangle.
A triangle has 3332 302 0 diagonals. Diagonal a² a² 2 a² which simplifies to. You can use the Pythagorean theorem to estimate the diagonal of a rectangle which can be expressed with the following. Just memorizing it.
