Difference between revisions of "Find the Measurement of the Diagonal Inside a Rectangle"

A diagonal is a straight line that connects one corner of a rectangle to the opposite corner<ref name="rf1">http://www.mathopenref.com/rectanglediagonals.html</ref>. A rectangle has two diagonals, and each is the same length.<ref name="rf2">http://www.mathwarehouse.com/geometry/quadrilaterals/parallelograms/rectangle.php</ref> If you know side lengths of the rectangle, you can easily find the length of the diagonal using the Pythagorean Theorem, since a diagonal divides a rectangle into two right triangles. If you don’t know the side lengths, but you have other information, such as the area and perimeter, or the relationship between side lengths, some extra steps will allow you to find the length and width of the rectangle, and from there you can use the Pythagorean Theorem to find the length and width of the diagonal.
