The minute hand of a clock is at 12 and the smaller hour's hand is at 2. The angle between the hands of the clock is

1

(a)

10°

(b)

20°

(c)

30°

(d)

60°

In the figure, ㄥACP=40 and ㄥBPD=120, then ㄥCBD=____________

1

(a)

[∵ Angles in the same segment are equal]
Now in ΔDPB
ㄥDPB+ㄥDBP+ㄥPDB=180°
⇒ 120°+ㄥDBP+40°=180°
ㄥDBP=180-(120°+40°)
ㄥDBP=20°
ㄥCBD=ㄥPBD=20°

In the given figure, if ㄥPOR is 110, then find the value of ㄥPQR.

1

(a)

Reflex angle PQR = 360° - 110°
= 360° - 110°
= 250°
By degree measure theorem,
ㄥPQR=\(\frac{1}{2}\)(reflex angle POR)
=\(\frac{1}{2}\)(250°)
=125°

The sum of the opposite angles of a cyclic quadrilateral is : ___________.

1

(a)

Sum of oppostie angles of a cyclic quadrilateral is 180°

In the figure, quadrilateral PQRS is cyclic. If ㄥP=80°, then R is equal to __________

1

(a)

Since, quadrilateral PQRS is cyclic
ஃ ㄥP+ㄥR=180°
⇒ 80°+ㄥR=180°
⇒ ㄥR=100°

Figure,O is centre of the circle and PA=PB Find ㄥOPA

1

(a)

Given PA=PB
∴ ㄥOPA=90^o
