Difference & Similarity between Square & Rectangle

Before you study this concept, you are advised to read: What is Rectangle ? There are two properties of diagonals of Rectangle Diagonals of Rectangle are equal. Diagonals of Rectangle bisect each other. Diagonals of Rectangle are equal This property explains that length of diagonals of a rectangle is equal So, if we know the length of one diagonal, length of other can be calculated. Example 1: In the following diagram of rectangle ABCD, diagonal AC = 5 cm. Find length of other diagonal BD. Solution: In the given rectangle ABCD: AC = 5 cm (given) Since, diagonals in rectangle are equal, so we get: AC = BD Put Value of AC (given) and we get: 5 cm = BD Or we can write it as BD = 5 cm Hence, length of other diagonal BD is 5 cm Diagonals of Rectangle bisect each other This property explains that diagonals of rectangle bisect each other at the intersecting point. In simple words, we can say that: Diagonals of rectangle divide into half at the point of intersection Example 2: Observe the following diagram: In the above diagram of Rectangle ABCD: AC and DB are two diagonals AC = DB = 7 cm Both diagonals AC and DB intersect at point O Since the diagonals of rectangle bisect each other at the intersecting point, so we get: AO = OC = Half of AC Since AC = 7 cm, so we get AO = OC = 3.5 cm Similarly, DO = OB = 3.5 cm
