Diagonal of a rectangle calculator


    • How do you find the angle of a rectangle?

      To find the area of a rectangle, just multiply the length times the width: Area = L x w. Opposite sides of a rectangle are the same length (congruent). The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a "right angle.".


    • How to make the rectangle go diagonal?

      You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w², and now you should know how to find the diagonal of a rectangle explicit formula - just take a square root: d = √(l² + w²). Our diagonal of a rectangle calculator allows you to use almost any units you want.


    • How do you calculate the diagonal of a triangle?

      To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse.
