In the above figure, Quadrilateral ABCD is circumscribing a circle with O and Ad perpendicular to AB. if radius of incircle is 10 cm, then,
Brother/Sister your correct answer will be:-
Step-by-step explanation:-
- Join RO
- Join OP
- Join OQ
Here, x = AB = AP + PB. We need value of AP and PB.
Beacuse we don't have direct method for finding value of x.
- Tangent at any point of circle is perpendicular to the radius through point of contact.
If three angles of quadrilateral ASOP are 90°. Then,
Thus, Quadrilateral ASOP is a square.
All sides of Square are equal.
ROQC is a quadrilateral and C is an exterior point of circle.
Lengths of tangents drawn from an external point to a circle are equal.
In quadrilateral POQB, B is an external point.
