1.Diagonals of a parallelogram intersect each other at point 0. If AO = 5,BO = 12 and AB = 13 then show that DABCD is a rhombus. |
|
Answer» Step-by-step explanation: Given: AO = 5, BO = 12 and AB = 13. To prove: ABCD is a RHOMBUS. Proof: AO = 5, BO = 12, AB = 13 [Given] AO2 + BO2 = 52 + 122 = 25 + 144 ∴ AO2 + BO2 = 169 …..(i) AB2 = 132 = 169 ….(ii) ∴ AB2 = AO2 + BO2 [From (i) and (ii)] ∴ ∆AOB is a right-angled triangle. [CONVERSE of PYTHAGORAS theorem] ∴ ∠AOB = 90° ∴ seg AC ⊥ seg BD …..(iii) [A-O-C] ∴ In parallelogram ABCD, ∴ seg AC ⊥ seg BD [From (iii)] ∴ ABCD is a rhombus. [A parallelogram is a rhombus PERPENDICULAR to each other]Read more on Sarthaks.com - https://www.sarthaks.com/849977/diagonals-of-parallelogram-intersect-each-other-at-point-if-ao-bo-show-that-abcd-is-rhombus |

In the following figure, ABCD is a parallelogram and BD is a diagonal. Find the value of r degree… |
Answer» Consider the DIAGRAM given in the question.As we know, the DIAGONALS of a parallelogram bisect each other. Therefore,⇒AC and BD bisect each other at point O. Thus,⇒OA=OC and OB=OD Now, consider POINTS P and Q. ⇒BP=PQ=DQ ---- (1)
(1)Now, since OB=OD, soPB+OP=OQ+DQFrom equation (1), DQ+OP=OQ+DQ∴OP=OQ Thus, AC and PQ bisects each other.Thus, APCQ is a parallelogram, because both the diagonals bisect each other. Also, since, CQ and AP are the opposite sides of the parallelogram APCQ, they are parallel to each other. |
