The diagonals of a rhombus are perpendicular bisectors of one another. Given: ABCD is a rhombus. To Prove: m∠ AOD = m∠ COD = 90°. Proof: ABCD is a rhombus. (Given) Since the opposite sides of a rhombus have the same length, it is also a parallelogram. .. (Properties of a rhombus) The diagonals of a rhombus are perpendicular bisectors of one another. Given: ABCD is a rhombus. To Prove: m∠ AOD = m∠ COD = 90°. Proof: ABCD is a Solution. Verified by Toppr. Let A(x,0), B(0,y), C(−x,0) & D(0,−y) be the vertices of the rhombus. We can verify by distance formula that AB= BC−CD = DA =√x2 +y2. In the above figure, you can see a rhombus ABCD, where AB, BC, CD and AD are the sides of a rhombus and AC and BD are the diagonals of a rhombus. Properties of Quadrilaterals. Types Of Quadrilaterals. Area of Rhombus. Difference Between Rhombus And Parallelogram Question. Using coordinates geometry prove that diagonals of a rhombus are perpendicular to each other. Solution. Let s be the length of the sides of the rhombus ABCD. Orient the rhombus so that its bottom side is AB where A = (0, 0) and B = (s, 0) and let D = (a,b) lie in the first quadrant Use coordinate geometry to prove that the diagonals of a rhombus are perpendicular. That is, write a coordinate geometry proof that formally proves what this applet informally illustrates. Be sure to assign appropriate variable coordinates to your rhombus's vertices!

Sal proves that the diagonals of a kite are perpendicular, by using the SSS and SAS triangle congruence criteria. Created by Sal Khan The two diagonals of a rhombus are perpendicular and bisect each other; Its diagonals bisect opposite angles; and. Opposite angles have equal Question. Using coordinates geometry prove that diagonals of a rhombus are perpendicular to each other. Solution. Let s be the length of the sides of the Use coordinate geometry to prove that the diagonals of a rhombus are perpendicular. That is, write a coordinate geometry proof that formally proves \(ABCD\) is a rhombus since it is a parallelogram all of whose sides equal 6. According to Theorem \(\PageIndex{1}\), the diagonals are Problem. In a rhombus ABCD, prove that the diagonals are perpendicular to each other. i.e prove that AC⊥DB. Strategy Problem. In a rhombus ABCD, prove that the diagonals are perpendicular to each other. i.e prove that Estimated Reading Time: 2 mins AD= CD [Sides of a rhombus] ∴ ΔAOD≅ΔCOD [SSS congruency rule] ⇒ ∠AOD= ∠COD (i) [CPCT] But, ∠AOD+∠COD= ∘ [Linear pair, since AOC is a

The area of the rhombus = 54 square units; one diagonal (q) = 6 units. We will use the formula for the diagonal of rhombus, p = (2 × Area)/q, where 'p' and 'q' are Geometry. Quadrilaterals. Parallelograms. Rhombus: Properties and Shape. Sides, Angles and Diagonals. Probably the most famous rhombus out there is the baseball diamond. The distance between each base is the same, making the shape a rhombus! More interesting math facts!
