1 answers

God'S Creation ....... 6 years, 3 months ago

Let 7+3√2 is arational number where 7+3√2=p/q and p and q are coprime numbers. 7+3√2=p/q. 3√2=p/q-7. √2=p-7q/3q. It shows that √2 is rational but we know that √2 is irrational.Hence our assumption is wrong by contradiction.

Porperty of cyclic quadrilateral

Posted by ? ☺ 6 years, 3 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 6 years, 3 months ago

Cyclic Quadrilateral Properties

In a cyclic quadrilateral, the sum of a pair of opposite angles is 1800. (supplementary).

If the sum of two opposite angles are supplementary then it’s a cyclic quadrilateral.

The area of a cyclic quadrilateral is [s(s-a)(s-b)(s-c)(s-c)]0.5 where a, b, c, and d are the four sides of the quadrilateral and the perimeter is 2s.

The four vertices of a cyclic quadrilateral lie on the circumference of the circle.

To get a rectangle or a parallelogram, just join the midpoints of the four sides in order.

If PQRS is a cyclic quadrilateral, then ∠SAR = ∠SQR, ∠QPR = ∠QSR, ∠PQS = ∠PRS, ∠QRP = ∠QSP.

If T is the point of intersection of the two diagonals, PT X TR = QT X TS

The exterior angle formed if any one side of the cyclic quadrilateral is produced is equal to the interior angle opposite to it.

In a given cyclic quadrilateral, d1 / d2 = sum of the product of sides, which shares the diagonals endpoints.

If it is cyclic quadrilateral then the perpendicular bisectors will be concurrent compulsorily.
