Diagonals of a Square

Diagonals of a Square
A square's diagonal is the hypotenuse of a right triangle with two equal sides. Use d = s√2 to find the diagonal from the side length.
Practice: solve for the missing measure, rounded to the nearest hundredth.
Square diagonal facts: the two diagonals are congruent, they bisect each other, they meet at right angles, and each diagonal divides the square into two congruent right triangles.
