CIRCLES
 
Q.- In Fig., if AB = AC, prove that BE = EC
Circles notes 11
 
Sol. Since tangents from an exterior point to a circle are equal in length 
∴ AD = AF     [Tangents from A]
BD = BE       [Tangents from B]
CE = CF       [Tangents from C]
Now,
AB = AC
=> AB – AD = AC – AD
[Subtracting AD from both sides]
=> AB – AD = AC – AF [Using (i)]
=> BD = CF    => BE = CF [Using (ii)]
=> BE = CE [Using (iii)]
 
Q.- In fig. XP and XQ are tangents from X to the circle with centre O. R is a point on the circle.
Circles notes 12
Prove that, XA + AR = XB + BR.
 
Sol. Since lengths of tangents from an exterior
point to a circle are equal.
∴ XP = XQ      .... (i) [From X]
AP = AR         .... (ii) [From A]
BQ = BR         .... (iii) [From B]
Now, XP = XQ
=> XA + AP = XB + BQ
=> XA + AR = XB + BR
[Using equations (i) and (ii)]
 
SECTION A:
 
1. A line touches a circle of radius 4 cm. Another line is drawn which is tangent to the circle. If the two lines are parallel then find the distance between them.
 
2. From a point P, which is at a distance of 13 cm from the centre O of a circle of radius 5 cm, the pair of tangents PQ and PR are drawn to the circle. Find the area of the quadrilateral PQOR.
 
3. In fig 1, if O is centre of a circle, PQ is a chord and the tangent PR at P makes an angle of 50° with PQ, then find∠POQ.
 
4. In the figure 2, QR is a common tangent to given circle which meet at T. Tangent at T meets QR at P. If QP = 3.8 cm, then find the length of QR.
 
5. In fig. 3, CP and CQ are tangents to a circle with centre O. ARB is another tangent touching the circle at R. If CP = 11 cm, BC = 7 cm, then find the length of BR.

6. Point P is 26 cm away from the centre O of a circle and the length PT of the tangent drawn from P to the circle is 24 cm. Then find the radius of the circle.
 
7. TP and TQ are two tangents to a circle with centre O such that ∠POQ = 110⁰. Then find ∠PTQ.
 
8. In the figure , QR is a common tangent to given circle which meet at T. Tangent at T meets QR at P. If QP = 3.8 cm, then find the length of QR.

9. If the angle between two radii of a circle is 100⁰, find the angle between the tangents at the ends of the radii.
 
10. From a point P which is at a distance of 13 cm from the center of a circle of radius 5 cm, the pair of tangents PQ and PR to the circle are drawn. Then find the area of the quadrilateral PQOR.
 
SECTION B :
 
1. Two concentric circles of radii a and b , where a>b are given. Find the length of chord of the larger circle which touches the smaller circle.
 
2. If d1, d2(d2>d1) be diameters of two concentric circles, c be the length of a chord of the circle which is tangent to the other circle, prove that d2 2 = c2 + d12.
 
3. If two tangents inclined at an angle 60⁰ are drawn to a circle of radius 3 cm, find the length of each tangent.
 
4. PA and PB are two tangents drawn from an external point P to a circle with centre O. If OP is equal to diameter of the circle, prove that ΔABP is equilateral.
 
5. A circle touches the side AC of ΔABC at P, touches BC at Q and AB at R. Show thatAC + AR = BC + BR.

6. If two tangents inclined at an angle 60⁰ are drawn to a circle of radius 3 cm, find the length of each tangent.
 
7. Two parallel lines touch a circle at points A and B separately. If area of the circle is 25 cm2, then find the length of AB.
 
8. In figure, if CP = 11 cm and BC = 7 cm, then find the length of BR.

SECTION C: 
 
1. In figure, a triangle ABC is drawn to circumscribe a circle of radius 10 cm such that the segments BP and PC into which BC is divided by the point of contact P, are of lengths 15 cm and 20 cm respectively. If the area of ΔABC is 525 cm2, then find the lengths of sides AB and AC.
