In Fig.7, `a=b=c ,` name the angle which is congruent to`/_A O C`

In Fig,8, /_A O C~=/_P Y R\ a n d\ /_B O C~=/_Q Y Rdot Name the angle which is congruent to /_A O Bdot

In fig.25,two of the angles are indicated what is the measure of \ /_A C D ?

In Fig. 10.36, A,B and C are three points on a circle with centre O such that \ /_B O C=\ 30^o and \ /_A O B =\ 60^o . If D is a point on the circle other than the arc ABC, find /_A D Cdot

In Fig. 15.98, A B C is a right angled triangle in which /_A=90o , A B=21\ c m and A C=28\ c m . Semi-circles are described on A B ,\ B C and A C as diameters. Find the area of the shaded region. (FIGURE)

In Figure, it is given that O is the centre of the circle and /_A O C=150^@ . Find /_A B C

If any two angles and a non-included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent. GIVEN : Two s A B C and D E F such that /_A=/_D ,/_B=/_E ,B C=E F TO PROVE : A B C~=D E F Figure

In Figure, O is the centre of the circle such that /_A O C\ =130^0,\ then /_A B C= (a) 130^0 (b) 115^0 (c) 65^0 (d) 165^0

In Fig., which of the following statements are true: (i) Point B is the interior of /_A O B (ii) Point B is the interior of /_A O C (iii)Point A is the interior of /_A O D (iv)point C is the exterior of /_A O B (v)Point D is the exterior of /_A O Cdot

In Fig. 6.13, lines AB and CD intersect at O. If /_A O C\ +/_B O E=70^@ and /_B O D=40^@ , find /_B O E and reflex /_C O E .

In Figure, A B C D is a rectangle in which diagonal A C is produced to E . If /_E C D=146^@, find /_A O B
