Class 10 Mathematics Chapter 10 Circles Worksheet Pdf

 

Q.- From a point P, 10 cm away from the centre of a circle, a tangent PT of length 8 cm is drawn. Find the radius of the circle.
 
Sol. Let O be the centre of the given circle and let P be a point such that
Circles notes 1
OP = 10 cm.
Let PT be the tangent such that PT = 8 cm.
Join OT.
Now, PT is a tangent at T and OT is the
radius through T.
∴ OT ⊥ PT.
In the right ΔOTP, we have
OP2 = OT2 + PT2 [by Pythagoras’ theorem]
=> OT = √OP2 - PT2 =√ (10)2 - (8)2 cm
= √36 cm = 6 cm.
 
Q.- Prove that in two concentric circles, the chord of the larger circle which touches the smaller circle, is bisected at the point of contact.
 
Sol. Given : Two circles with the same centre O and AB is a chord of the larger circle which touches the smaller circle at P.
Circles notes 2
To prove : AP = BP.
Construction : Join OP.
Proof : AB is a tangent to the smaller circle
at the point P and OP is the radius through P.
∴ OP ⊥ AB.
But, the perpendicular drawn from the centre of a circle to a chord bisects the chord.
∴  OP bisects AB. Hence, AP = BP.
