Class 10 Mathematics Chapter 10 Circles Worksheet with Answers

 

CIRCLES

Q.- If radii of two concentric circles are 4 cm and 5 cm, then the length of the chord of one circle which is tangent to the other circle is: 

WT_circles test 23

a. 9 cm

b. 3 cm

c. 1 cm

d. 6 cm

Ans- d. 6 cm
Explanation: Here OC is perpendicular to AB.
Then OC bisects AB i.e., AC = BC
Now, in triangle OAC,OA2=AC2+OC2
(5)2 = AC2 + (4)2 AC2 = 25 - 16
AC = 3 Therefore, length of tangent AB = AC + BC = 3 + 3 = 6 cm
 
Q.- A circle is inscribed inΔABC having sides 8 cm, 10 cm and 12 cm as shown in the figure. Then the measure of AD and BE are... 
WT_circles test 24
a. AD = 8 cm, BE = 5 cm.
b. AD = 8 cm, BE = 6 cm
c. AD = 5 cm, BE = 7 cm
d. AD = 7 cm, BE = 5 cm
 
Ans- d. AD = 7 cm, BE = 5 cm
Explanation: Let AD = and BE = y
∴ BD = 12 - x BE = y
But BD = BE (Tangents to a circle from an external point B)
=> y = 12 - x
=> x + y = 12 ……….(i)
Also, AF = x
and CF = 10 - x
and CE = 8 - y
∴ 10 - x = 8 - y
x - y = 2……..(ii)
On solving eq. (i) and (ii), we get
x = 7 and y = 5
Therefore AD = 7 cm and BE = 5 cm
 
Q.- At which point a tangent is perpendicular to the radius? 
 
Ans- A line which intersects a circle at any one point is called the tangent. The tangent at any point of a circle is perpendicular to the radius through the all point of contact.

14. Prove that parallelogram circumscribing a circle is a rhombus. 

Ans-

WT_circles test 25 

Given ABCD is a parallelogram in which all the sides touch a given circle
To prove:- ABCD is a rhombus
Proof:-
∴ ABCD is a parallelogram
∴ AB = DC and AD = BC
Again AP, AQ are tangents to the circle from the point A
∴ AP = AQ
Similarly, BR = BQ
CR = CS
DP = DS
∴ (AP + DP) + (BR + CR) = AQ + DS + BQ + CS = (AQ + BQ) + (CS + DS)
=> AD + BC = AB + DC
=>BC + BC = AB + AB [ AB = DC, AD = BC]
=>2BC = 2AB
=>BC = AB
Hence, parallelogram ABCD is a rhombus
 
Q.- A quadrilateral ABCD is drawn to circumscribe a circle. Prove that AB + CD = AD + BC. 
 
Ans-
 
WT_circles test 26
∴AP, AS are tangents from a point A (Outside the circle) to the circle.
∴ AP = AS
Similarly BP = BQ
CQ = CR
DR = DS
Now AB + CD = AP + PB + CR + RD
= AS + BQ + CQ +DS
= (AS +DS) + (BQ + CQ)
= AD + BC
AB + CD = AD + BC
 
Q.- In given Fig. XP and XQ are tangents from X to the circle with centre O. R is a point on the circle. Prove that XA + AR = XB + BR. 
WT_circles test 27
 
Ans- Since the lengths of tangents from an exterior point to a circle are equal.
XP = XQ ..........(i)
AP = AR ........ (ii)
BQ = BR ......... (iii)
Now Xp = XQ i.e. XA + AP = XB + BQ
XA + AR = XB + bR
Hence proved.
 
Q.- In the given figure, find the perimeter of ABC, if AP = 10 cm. 

WT_circles test 28

Ans- BC touches the circle at R
Tangents drawn from external point to the circle are equal.
AP = AQ, BR = BP
And CR = CQ
Perimeter of ΔABC = AB + BC + AC
= AB + (BR + RC) + AC
= AB + BP + CQ + AC
= AP + AQ = 2AP = 2 ×10 = 20 cm

KEY POINTS

1. Circle: The set of points which are at a constant distance from a fixed point in a plane is called a circle.R

2. Circumference: The perimeter of a circle is called its circumference.

3. Secant: A line which intersects a circle at two points is called secant of the circle.

4. Arc: A continuous piece of circle is called an arc of the circle.

5. Central angle: - An angle subtended by an arc at the center of a circle is called its central angle.

6. Semi-Circle: - A diameter divides a circle into two equal arcs. Each of these two arcs is called a semi-circle.

7. Segment: - A segment of a circle is the region bounded by an arc and a chord, of a circle.

8. Sector of a circle: The region enclosed by an arc of a circle and its two bounding radii is called a sector of the circle.
